Unfortunately
@wicknix it's right.
We have to stop thinking about Linux (or any other OS, *NIX or not) like it's the savior or the magical solution of computing.
All huge companies would make anything to lock their "solutions" and make their users prisoners without any alternatives, so we as users should take control of our files, protocols, systems, technology etc.
DropBox and Gdrive are mostly an WebDAV (FTP or rsync), with some "fairy dust" in warped with some "fancy design",some useful and convenient tricks to make us forget how things actually works behind the curtains.
So, if you wanna continue to use those solutions you will continue to switch OS's from time to time, a newer version of OSX, Windows, Linux with flatpacks(because it's way more easy to make "an executable" than it's to make your source code and documentation available).
Because if you can access your files through any file explorer and sync it, you can do this with almost any OS (mobile or desktop) and not depend on their solutions. And using any browser to to this will require much more resources than many of real apps combined.
With the current and future landscape of selfhosting being in charge of our files will become a question of choice, but that's leave it for another day.
