they have not blocked it and they probably won't block it bc it involves signing in with your twitter and since it's just an android app it's not gonna get as big as nitter, I don't think it's really helpful to tell people to "just accept it" as an individual you're not gonna be able to successfully lobby everything you follow to change to bluesky (which I think you can get rss feeds from) or masto (which you can get rss feeds from), like for example your city's local government/services only posts on facebook and twitter, no rss, this is still useful for things like that

Twitter is very much not dead, unfortunately.
