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

If you’re asking this you should probably use one to be more safe if you’re exposing stuff to the web, there are other ways of doing it including just VPNing into your home network or using a VPS or cloudflare tunnels, but using a reverse proxy manager in combo with cloudflare DNS is a good place to start and is probably good enough if you use good enough security with it: long unique passwords, two factor, security keys, etc.
