Just stop using Meta products. It's really not as hard as it seems. Nobody needs FB to communicate with friends and family. Send texts or emails or use your phone.
The hardest part about not using Meta products is deciding not to use meta products. When I stopped using Facebook, I had resigned myself to spending a lot of time and effort to stay in touch with my friends and family. As it turns out, all I had to do was mention that I was using Signal, and the people closest to me, then pretty close to me, then kinda close to me all started using that too. The network effect cuts…
If someone is prepared to not be my friend because they only want to communicate via a Meta app, then I don’t see why I’d want them as a friend.
