I haven’t used Facebook in years, but I still use Twitter because most lefties and furries I follow either haven’t moved to Bsky/Mastodon, or have moved but are inactive.
I still have an account on Bsky though, but I don’t use it that often.
Somehow I still haven’t seen that message despite also using uBlock and Firefox. Perhaps I’m just further down the line and Google will eventually come for me too, but I wonder if my DuckDuckGo and Privacy Badger extensions may also have something to do with it.
