But whatever changes are made to the OS, it wouldn't be to the point where software developed for the Steam Deck would be incompatible with Linux.
You can not be sure of that ;)
It's in Valve's best interest to ensure that more gamers switch to Linux as opposed to Windows, since Microsoft is heading in the direction of a walled garden ecosystem, especially with ARM.
I do not believe that. It’s in Valve’s best interest to ensure that more gamers switch to SteamOS
rather than anything else. And for that is does not matter if SteamOS is built upon Linux, some *BSD or even Fuchsia, the new Google OS.
All they want is an exit plan in case Microsoft no longer gives them full access to Windows users. But until then, they have no issue at all with Windows. SteamOS is used as a pressure tool against Microsoft, not as some way to help Linux users they never did care about.
Sure, they can do whatever they want obviously. But for now they are allied with Linux ecosystem and do a lot more than anyone else to advance it. (…)
I’m quite sure you remember that a lot of Linux users were saying exactly that about Google not so long ago ;)
