I think she's become more controversial because she's become more popular and more of an influencer in the past few months. I don't get the freakout about her going to the supermarket one too many times but can understand the annoyance about not declaring it AD as she should. Anyway, she makes mistakes like everyone else but I wouldn't call her immature either. I do like reading what other people think and what they would like to see more of her doing.
I think this is maybe because we have high expectations of her? She didn't do ads, she did lots of really great content that was just around her house (giant bean bag, modelling photos etc), and with all her volunteering and just seeming like a nice, happy person, makes us expect more. I was personally quite annoyed by all the trips to the shops, because for the last year I've very carefully planned the shop for the whole family, figured out meals, made sure we have everything in for a week, then only go to the shop super early in the morning to avoid people. And it feels like this would have been something Grace could do and make interesting. I was fully expecting (and would love!) to see her come up with a plan for a week of food. I'd love to see what she does when she's running low and only has a few tins in the cupboard. I really loved her crafting videos, when she was trying to find things like that to do. I guess she has that child-like fun quality I was hoping she'd inspire me to find ways to enjoy lockdown and instead it annoyed me that she was popping to the shops or for drive-throughs every other day and meeting up with friends and still having siblings over when we don't get to do that. And in terms of the ads, I don't think any of her followers would care one bit if she was doing proper ads, they're annoyed by the trying to hide it, not the actual ad!
