Because we can't implement every change at once. Just degoogling is tough as hell. I still have an account I use on a really old laptop for dealing with work and the gov just to appear conformist.
Then we have to change email, figure out vpn, find alternatives for everything under the sun, figure out what Linux we can live with and how to maintain it. What phone to buy, how to keep google away from it and Facebook from hiding under every damn thing too.
Going as fast as I can and still be sane. I'm tired boss.
