My understanding is, that there isn't an email privacy, since at least they will have your metadata. In my limited understanding, secure communication is to be done using some secure chat service.
I'm also fairly sure that Google will start integrating PGP into their desktop clients (Android, iOS) because this is affecting their bottom line (just wait until governments will start banning Gmail usage in the public sector).
people aren't JS libraries, you can't/don't "just move away from them"
"Hi Mom, I just want you to know: I am deprecating our relationship to "acquaintance" because you use Gmail and an iPad"
E.g. here are mine: not enough people communicate securely right now. I can't just abandon everyone; that's way too isolationist for my personal taste. Still, if you want to that _is_ an option.
