A majority of the things that sponsor YouTube videos. As great as much of that stuff is, one must not forget the reason many people advertise products online is to serve as a loophole when something about it is too questionable for the stores. I previously mentioned MagicSpoon cereal for example, and as good as it might be in moderation, it's a well-known FDA nightmare because things with artificial sweeteners are so antsy to get themselves on shelves. Probably my favorite example though is Established Titles, which I'm known to simultaneously make fun of often, point out how over-the-top it is with its scammy reputation, and admire its intentions since it's technically trying to help in ways that surpass Ecosia (and to the next person who replies to this, that's Lady Leni to you!)
