Just after last privacy changes, that is no privacy? Go android
I agree that Meta’s products in general are despicable. But not all my friends have switched to Signal/OpenWhisper during the fallout so I still need that crap to communicate with the remaining ones.
At least getting rid of the closed-source android step would be a tiny step in the less-wrong direction, even if in a perfect world, everybody should be using some open-standard of federated messaging (like matrix).
