On another note, tags are the resonsibility of the publishers. This has drawbacks. Like devs not tagging their stuff at all. Or having different opinions what a tag stands for or if it applies. Or what qualities should or should not be tagged. There are people tagging indie on itch...
The freedom of tagging also means, that there are heaps more tags than on Steam, where there are only pre-defined tags. And I think they are at least in part chosen by the users.
