To address your Proton Drive comment directly, they are a small team and they are rolling out Web, iOS, Android, Windows and Mac. The most common platforms today which is what they should focus on. Android already has photo backup, iOS it's in beta. They are continually having new releases for all of these products and you can see that on /r/ProtonDrive. Saying they have abandoned these products or don't care about them is hyperbole. Is it taking longer than I would like, sure, do I want them to release a Public API for Drive (for rclone) and a Linux client, absolutely but lets give teams the benefit of the doubt.
