@foxhkron @hj @SuperDicq Valve frankly does not care about the popularity of LiGNUx - it's purely a business decision.

"Powered by" is not correct when it comes to Linux - that kernel frankly mostly schedules processes and does stuff like packet routing.

Valve knows that microsoft is desperate to make software installing on windows be only possible via the microsoft store - so they can charge a fat 30% like apple and google.

Valve also knows that microsoft will eventually succeed despite their bungling.

So, Valve looked for the most technically suitable OS available and for "no particular reason" found the GNU OS with Linux added and determined that how Linux being proprietary just doesn't soil GNU enough - they would go and soil it with more proprietary software, with the eventual result of sales no longer being dependent on microsoft.
