Opinions on YouTuber CoCoCrazy

They have a few videos criticizing some designs of MGA. They view nanana surprise, lol omg surprise and unicorn poopsie dolls as inappropriate for children.

Full disclosure don't have children yet, but I don't really see an issue with these toys. The YouTuber seem to think that the lol and Nanana dolls are inappropriate for having underwear. As a kid I thought dolls without underwear were weird. So I don't see an issue with those doll brands being sold to children. The unicorn doll is gross and if I was a parent I probably wouldn't buy it. I don't want to clean sparkly slime off everything. I don't think they're necessarily inappropriate and think it's weird that some adults are them. However I don't see any adult themes with this brand and it gives me the ick that some adults are. Gross out humor is common with kids. I think that's all that was behind the poopsie brand's design.

What are your thoughts on the subject, MGA or the YouTuber mentioned?
