I still have to use WhatsApp for my international family. That is what they use. My mom also still uses Facebook Messenger and won't move to something else. I think it is because she uses it on her tablet and WhatsApp won't work on it. I tried getting everyone to move to Signal but I was very lonely on that hill. I have FB account but I rarely every check it (once in every six months or so). I got off in 2018 after I felt so angry over something political in the US and realized that FB was making me angry on purpose to get clicks. I never had Instagram. Got into Pixelfed and I'm enjoying it a lot (perhaps because I have no prior benchmark with Instagram).

I've been quite concerned with Meta since I read "The Chaos Machine" by Max Fischer which goes into detail about how FB was heavily responsible for the ethnic cleansing of the Rohyinga in Burma.

I once read a series of articles where someone gave up using one of the big five tech companies (Google, Facebook, Amazon, Apple, Microsoft) for one week each. It was interesting how hard it was do with some. Facebook and Apple were the easiest but Amazon was nearly impossible because of AWS. I've concluded that for me, I can minimize my Facebook, Google, and Amazon use as much possible but in the end, just have to live with Microsoft and to a much lesser extent Apple for time being. But to each their own.
