As a viewer I think maybe it's the way it's done. Quite often (and I'm not on YouTube much so maybe wrong) people may show make up they are sent or products to try and it's almost like a review?! This means a) you can choose not to watch b) you may be interested in how the product works or tastes etc
On Instagram ads are often hidden and it's just a freebie promotion. Rather than give us a review (say of Dorset Cereals) it's just promotion. I think maybe people find it more irritating and feel they are being used for someone to just flog at them and make money. Even if the kids said ugh we hate this one and the adults said, actually we really like this one, it would be keeping it more real than a bizarre family set up of children with empty bowls. MOD quite often used to recommend products she had bought and used which was interesting and I assume gained her the position of 'influencer' she had now, but that's not really what they do with their freebies. The free hotel was used in a must have time away from kids (which lots of us simply can't do) but then you have motheroffiveboys walking round showing you accommodation and views and really reviewing and giving insight. (Don't actually know if they are given these accommodations or if they pay just pointing out what feels more real as a viewer) I'm aware they don't give a monkeys what a viewer like me thinks but this is a discussion about instamums accounts.
And regarding discussion, if someone finds something really smug or that a tone has changed or that they feel like something is irritating, why is it wrong to discuss it? It's so weird all the people who come on to shut down discussion. I didn't call FOD a wanker, but he's thrived off it, he doesn't give a crap. And if they put their opinions and thoughts out there why can't people discuss and disagree?
