like what if linux still was open source but had a lot of proprietary dependencies and packages and became more popular and therefore proprietary software came to it?? but it still would let you use any desktop environment and there would be a new proprietary desktop environment which was like gnome but easier
Its not proprietary but flatpak is "taking the android route" as in providing a "app store" with sandboxed apps and standardized runtimes whose permissions can be limited and expanded at runtime by requesting the user. they already have a system for tipping devs and IIRC also wanna include a way to pay for apps.
The proprietary version of this would be Ubuntus snaps, but since the proper functionality of them is limited to ubuntu as the only distro i doubt they will take off
