The problems with privacy is that for every 1 person who cares  and try to stay protected there are 150 that don't give a flying duck about it, and if you want to communicate with some of that 150 you have to go mainstream. I tried using minds when was released, as alternative to social media where you get organic and not manipulated post, and till this day I don't have any friends who are using it. So no matter how you try there will always be some weak spots.
