This. please just finish all your other offerigns. Proron drive still does not have a linux desktop app. Proton VPN’s desktop app is beoken half the time. No mail desktop app…

Here is how I done it:

Email, drive - Proton (+vpn)

Youtube: (NewPipe/Libretube)

Phone OS: CalyxOS/GraphineOS

Maps:Organic Maps (powered by OSM).

All of these are open source.
