I think OPs posts on this thread do come across as very judgemental of parents today!
I don't agree that parenting has become easier. Yes, we have Google and washing machines and cars and disposable nappies; so in a practical sense, parenting can be easier in some ways. But I think society continually raises the bar as to what it means to be a "good parent". Nowadays we can't leave our kids with a local teenager as a babysitter, we shouldn't let our kids disappear off to the park all day with their friends, we have to worry about their screen time and social media access. We're told to breastfeed and be responsive to our baby's cries; no putting the pram in the garden for a few hours or putting them in the cot at 7pm and closing the door for the night.
I'm not saying parenting is harder either - maybe it is more mentally taxing, but running a family home is now physically less demanding? Every convenience that comes along seems to have an equal and opposite new problem to deal with, so nothing gets easier?
As to expectations on grandparents, I'm sure there are unreasonable behaviours on all sides in some families - but it comes down to communication, if grandparents are unhappy they need to voice that and seek a resolution?
We are lucky to have two days of childcare from grandparents. This was offered, not requested, and we have offered money (turned down) so try to ensure we show appreciation via presents/meals out/invitations to join us on weekends away. That said, we have also occasionally had to have a gentle word about issues e.g. grandparents being late in a morning. If grandparents took offence to this, I would be sad, but ultimately we would be happy to put our children into nursery more days a week if necessary - I dont think its unreasonable that if grandparents choose to do regular childcare, that childcare needs to be reliable and meet the needs of the family (I.e. parents get to work on time)? Equally, if the grandparents want to stop at any time they can do (we have told them this) but - emergencies excepted - we would need notice to find new childcare. And if they were to stop offering childcare, they would see us and our children less - that's not us being unreasonable, but there are only so many hours in a week and they might have to settle for one Saturday afternoon a fortnight for example, rather than a full day every week?
I agree that some parts of the article you have quoted do sound a bit ridiculous, but thats what journalism is now - designed to bait people! And it's worked 🤣
