I don’t really pirate anymore, but have been using ProtonMail, Proton Calendar and ProtonVPN for a few years on pure privacy grounds, and generally really like it. Their apps have gotten more stable over time and their bona fides are solid (actually fighting against subpoenas, etc).
They are actively improving things like calendar invites and integration in their suite of apps. Between that and ente for photo storage I’ve mostly degoogled myself over the last couple years.
