yes. husky in particular is a fork of another app called tusky, that internally implemented a login blacklist of explicitly-nazi instances and instances with lolicon content, after the author decided they didn't want those users running their software. husky's explicit sole purpose is to be tusky without that blacklist. tusky has not been removed from the play store.

i'm not familiar with the other apps on the list but i expect it might be some issue like promoting such instances in their registration screen.

also interestingly, the instance OP links to qoto.org is known within the fediverse for being full of creepers, because they've implemented a partial defederation and block circumvention. if you have an account on qoto.org, you can follow users who've blocked you, on instances that have blocked you, because it will recognize such, pull a list of posts via RSS instead of via activitypub, and fake an activitypub actor internally to generate posts for your feed. in their defense they have said that the posts are public anyway, and the user could just browse the public feed with a web browser, but it's clearly a bit different when posts from a person who has tried to block you appear in your feed normally as an item you can interact with. it's certainly against the spirit of consent.
