In my case, privacy is not the main issue because I have been self-hosting almost all my services for many years. It is about what is just, moral and right according to my own principles : honesty, respect, trust and fairness.

I don't want to continue to contribute to making richer companies that try in every possible way to steal data and wealth from their customers and other nations with unfair behavior at the edge (or beyond the edge) of the law.

And if that is not enough to also use every possible way to manipulate the people's beliefs with false claims and evil psychological tactics.
