I don't like Google, the company, and if there is an easy option to migrate to that will cause me the least usability issues, I'll migrate.
Call me a lazy activist if you will.
Any good alternatives that don't look like webmail from the 90's?
Another option could be to skip webmail and use local clients instead, like Mail.app or whatever you fancy.
Idk about your style preferences though.
