Not much that we can do unfortunately. All those hearings went nowhere.
Personal stuff such as stories, selfies and videos? Indeed. But, stuff like private messages (which aren't private, lol) are needed, to contact your friends, co-workers, employers etc. I don't say there aren't alternatives, but since that's what most people use, you're, essentially, forced to have it too.
Hence the need for alternatives. The problem though is that those either get killed in the cradle or taken over.
Is there anyone in this year still using Facebook? it's a cringey social media with full of old people who posted his daily activity to expose their privacy.
Now Instagram is the most biggest social media, but it's linked with Meta aka Facebook, so the best way is avoid social medias that has collect your data.
It's still pretty big here in the developing world. Politicians here even pay trolls to harass opponents supporters there.
