It’s always interesting when someone is like “I wish I could go back to using smaller sites/forums or try some more open/ethical platforms, but I can’t because all of my family are on Facebook.”
Remember just 20 years ago when most of your family wasn’t anywhere on the internet and that was just fine? I recognize that I’m saying this as a semi-isolated weirdo on some relatively obscure corner of the Internet, but it’s okay to not be in constant passive contact with everyone you’ve ever met. Yeah it’s more work to keep in touch with the folks you actually care about if you can’t do so passively via Facebook, but that’s how it always was. Email exists, texts and phone calls exist, meeting up exists.
If there are people you care about you can still keep in touch with them without using the same social media platform as them. Just like in the 90s you didn’t need to read rec.models.railroad to keep in touch with your model train loving uncle.
I get that these connections (whatever one might say of their quality or tangibility if the interaction is just “look at picture, press like button”) are important to people and one of the positives of platforms like Facebook, but if you’re going to bemoan not being able to seek alternatives solely because the entire world isn’t switching with you, it’s important to realize that is a choice and not a requirement.
Broadly speaking it sounds a bit like Antitrust https://en.m.wikipedia.org/wiki/Antitrust_(film)
But I haven’t seen it in quite a while so I’m not sure how well specifics line up.
