I'm getting ready to move off of Google (and Private Internet Access), and Proton is looking like the best option. But I'm nervous. Some of the things I worry about:

• Calendar support: I rely really heavily on Google Calendar. How will I share events with others? And what will I do without Google Tasks?
• VPN App Quality: Seeing some mixed reviews on Proton VPN Android app.
• Proton ethics & politics: Look, I really don't want to open up the holy war here. My big stipulation is: I don't want my money to go to a company that will donate its money or services to fascists. To my knowledge, Proton does not do that. I know they made a post that seemed to praise GOP antitrust efforts. I do not believe that that is the same thing as lending material support for fascists. (And, as someone who is very well read-in on antitrust issues, I'll say that -- for a lot of complicated reasons -- there is some truth to Proton's post, but I wish they had framed it as a critique of the corporate wing of the Democratic party and not praise of the GOP.)
• Anything else I haven't thought to ask.

So, folks who have made the switch: What do you wish you had known? What do you wish you had done to make the move easier?

Thank you for your advice.
