It's not about relying on others to figure it out for them. There are multi-level barriers to breastfeeding in modern UK culture.
In past generations, long back, we would have had mothers, sisters, aunts, neighbours and grandmothers all who would have breastfed (or 95% of who would have breastfed) and they would have been around to give advice and support.
Most babies were breastfed and people had large families so people saw breastfeeding happening. We know from research that women who grew up with breastfeeding or whose family members breastfed are more likely to be successful at breastfeeding themselves. This suggests that there are factors to breastfeeding success which are not reliant on a google search or reading a book or knowing something. It's something innate that you pick up in childhood, and/or the fact of having family and friends around you who support and understand breastfeeding, rather than challenging it.
We live in a bottle feeding culture. Most people are more familiar with bottle feeding than breastfeeding. When we hold a baby in our arms we tend to naturally hold them on their backs with their tummies facing up. For successful latching you need to hold a baby with their tummy facing you. But that's not something you'd think to google and despite doing lots of research myself before birth it was something I had to be shown. Of course, once you do it and think about it, it's clear that a baby can't drink while turning their head to the side, but nobody thinks about drinking in that much detail.
When most of your family has bottle fed and they are surrounding you after the birth of your child with love and support you do not google every piece of advice they give you. When your aunt, who's brought up 4 children, shows you a winding technique or something that makes your baby laugh, and you copy it and it works you don't then google to check that it's the correct up to date scientific method. Likewise when your mum says something like "He can't be hungry again; you've just fed him. Let's try this instead." You're not likely to hop onto your laptop immediately and fact check. You'll take it as a given that her advice is sound because, after all, she raised you just fine. Why should breastfeeding need extra research? No other aspect of baby care needs fact checking. If you're not aware of the fact that older generations may have been given false information about breastfeeding you're not likely to check up on it unless it feels wrong to you. No new parent is an expert with babies, we all seek help and advice from others whether that is friends, family, books, internet or medical professionals. Most people use a combination but some people tend to lean more to real people and others tend to lean more to theoretical information.
Additionally, when you're in hospital you might not have access to books and the internet. (I got no 3G signal last time I was in hospital, so even having a smartphone didn't help). You're exhausted from birth, probably in pain, perhaps traumatised or shocked and it's very overwhelming. Again, even as a person myself who had done a lot of prior research I suddenly felt like I had forgotten everything and I didn't know what to do. A picture in a book (or a leaflet which is what I was given) is really useless when you're faced with an actual squirming, also shocked, also exhausted, also overwhelmed newborn who's just experiencing things like light and air currents and unmuffled sound and being picked up and wearing clothes for the first time. You're scared you might hurt or break them and they don't naturally latch like the book says. I think most women need somebody to sit with them and get them calmly through it the first time, perhaps for several times after that. As Golden pointed out, the stuff about the golden hour after birth and the breast crawl is fantastic - but not possible under the time constraints in an NHS hospital. So you're not likely to have that "best standard" start, and it's somewhat of a lottery whether you'll get somebody who can sit with you and calmly help you (and this is if you have a baby who will latch and no further issues) or whether you'll get somebody harrassed, pushed for time who will thrust a leaflet at you or just tell you patronisingly to "Keep trying, you'll get there!" with no actual help. If the baby doesn't latch easily, again it's a lottery, you might get somebody who has the time, patience AND expertise to gently coax them to do so but the three things are in short supply, and you'd be lucky to find all three. (I was lucky; I had a baby who latched easily and a midwife who had time and expertise.) If you're unlucky you'll get bad advice or "help" which is actually invasive and counterproductive, causing more issues.
This does not even go into situations which make establishing breastfeeding even more difficult. Perhaps the mother and baby were separated due to difficulties at birth, infection, c-section recovery, etc. Perhaps the baby was very sleepy due to pain relief the mother had during labour. Possibly the baby was born early, late, low birth weight, jaundiced, other factors that mean it's more critical to establish feeding quickly. This can drain the time and patience of HCPs and up their urgency which leads to anxiety on the part of the mother. I'm not even going into rare cases, these are all fairly common occurrences.
You can't differentiate good advice from bad at that point, and nor should you have to. Can you not see what a huge task that is to put onto somebody?
Then lastly even if somebody does want to question advice from their family or friends, from health care professionals, or general assumptions that they hold (which might not even be conscious beliefs, so I'm not sure where you'd start with researching that) there is an ocean of "advice" relating to breastfeeding on the internet, there are several books, all varying in their usefulness. It takes a long time to search through all of these and understand what is correct and what is false. You can't tell at first glance which websites are trustworthy and which are promoting bad information in good faith. You claim that bleeding nipples are "easily remedied with a google search" but actually while most websites emphasise the need to seek support many of them are cluttered with useless suggestions like "Apply a cold pack before nursing to numb the area" or "Use an antibacterial ointment" "Pump and bottle feed for a day" but also "Nurse more frequently, at least every 2 hours" - perhaps all suggestions with merit in certain situations, but not particularly helpful as an assortment, and again, confusing and overwhelming - it is a big ask to expect a complete beginner to be able to work out which exact solution is useful in her particular situation, whether it's a permanent or temporary solution, and what to do next if it's temporary. You wouldn't get this with anything else. Books can be even worse - with many bestselling babycare books containing terrible advice about breastfeeding which is just incorrect.
Bad advice - whether from a hurried HCP, well-meaning family member, misunderstood website, misinforming book, taken early and followed in good faith can lead to further problems which then gets you on a downhill path where the lower you get the more problems you encounter which makes it harder and harder to continue. It's possible to come back from that but only if you recognise you're on it to begin with, and/or only if you find the right path back up, which might happen by luck or might take some identifying. Which, again, is expecting a huge amount from a person who is a complete beginner to all this and probably wasn't expecting to need a PHD in it before they started, especially as the bumf you get given in pregnancy just talks about how natural and healthy and bonding and wonderful it is.
And did I mention you are doing this on NO sleep. With hormones crashing around. With a painfully contracting womb. With stitches. Perhaps with reduced mobility. Possibly with PND. Likely (if you're having issues breastfeeding) with shredded nipples, which you don't especially want to talk to strangers about.
Yeah, sorry, but in no way is a woman struggling with breastfeeding lazy, entitled or any of it. If you can't see any of this scenario as being a human who just wants some help and a person they can trust, then I wonder about your empathy, because I think it's a horrendous situation to put women in and I find it totally shocking. Put the mechanics of breastfeeding in the national curriculum along with the rest of human reproduction, give midwives and health visitors a decent grounding in realistic BF support, not "best case only" BF support, allow voluntary organisations to support in hospitals, whatever, it doesn't have to be expensive or complicated. Women should not be expected to find this information out for themselves.
