Valve is not forcing us to run steam.
Valve runs the DRM that runs Steam. They are making the platform desktop agnostic, but that may not be sustainable.
Also what the hell do you mean by consumer linux is steam¿?
After the release of the Steam Deck, Linux on Steam has seen an increase so large that it now beats Apple for the #2. Steam may push users to Linux, but still run the Steam walled garden.

Sure, but they can’t force Linux users to use Steam. It just so happens that most Linux gamers use Steam because it works well for them, thanks to the hard work of the various open-source devs (along with Valve, Codeweavers, etc) behind WINE, DXVK, and Proton. Microsoft can theoretically force Windows users to use only their store, if they felt like that was a good idea for whatever reason.

The Steam Deck has both a Desktop Mode which lets you run any application you want (so long as its Linux compatible of course), SteamOS is built on top of Arch (which you can build on top of), and lets you run whatever OS you would like (you can even go as far as removing SteamOS if that is what you want). I’m not sure how it’s a “Walled Garden”. A walled garden would be the Xbox / PlayStation / Switch and basically any other console, along with most mobile phones, where you cannot install the OS that you want - you’re forced to use what the manufacturer provides.
You can use Android without Google Play Services and people do, but the vast majority of people using Android use Google Play Services.
I can see that happening to Linux on the desktop if the main driver is Steam.
There’s a huge difference between GPS which is effectively a rootkit, and Steam which is a userland application however. To actually remove GPS requires that you have a device with an unlockable bootloader (or an active exploit to gain root privileges) so that you can flash a ROM without it - Steam is one simple uninstall away.
Sure, a monopoly on the gaming market isn’t great, and while I hope I don’t bite my words anytime soon - Valve/Steam is the lesser of the two evils. Especially if you consider that it wasn’t really all that long ago where Linux gaming was an absolutely crazy idea that resulted in the pool of games available to you to be very very small.
