Yes and yes.
After about 20 years on Facebook, I deleted my account there a few months ago, when they announced that they wanted to add AI that would scape user profiles. I had deleted my Twitter account after Musk bought it and turned it into an online Nazi bar. (I gave up Myspace a long while ago too.)
Microsoft seems to want to add "social" functions to LinkedIn, but I don't want to even "like" any political posts there.
I like the community I find here on Mastodon.
