Why YSK: because, one, Facebook/Meta is a huge player in the tech industry and it's totally unacceptable that they are continuing to be allowed to operate like this, I'm trying to raise awareness because most people have some idea that Facebook is bad, but few know the details on how and why and to what extent they're so bad. Also, Facebook is releasing a Fediverse compatible platform, so their presence will very much affect the Fediverse, including Lemmy.
Just the requirement of requiring Instagram to sign up for threads and use of their app with so many permissions should be enough of a red flag for those unaware of meta's history.
