CDPR just doesn't see the demand
Exactly the point to show them some. They aren't really looking for demand (Steam survey isn't the source for it, as many quite explicitly explain).
According to former VP employee who worked on TW2 for Linux, this has nothing to do with demand, but with their plans to tie TW3 for Linux to Steam Machines. I.e. I suppose they thought Valve as the vendor to associate with Linux as a platform. Like I said above, this platform mentality dominates gaming business, and anything outside of this bracket looks completely foreign to people in it. So when Valve basically stopped actively pushing Steam Machines, CDPR cancelled TW3 for Linux. That's according to that former VP source.
In practice of course Valve's actions didn't make Linux gaming any smaller - it only has grown since then, but since it's not vendor framed, legacy publishers have a headache with wrapping their mind around it. And CDPR said in the past, they aspired to emulate gaming bigwigs, which unfortunately looks like applying to Linux gaming as well.
The reason I get tired of this circle is because it is the -same- circle. Nothing has changed.
Many things have changed, and I already explained above how. It's intellectually dishonest to claim that nothing has changed in Linux gaming comparing to the past. It doesn't help the conversation to ignore the facts.
If CDPR announces something Linux related, fine. Until then, using the forums to promote your particular pipedream isn't what they are here for. Unless that pipedream is -directly- cyberpunk related.
CDPR are quite weak in communication (we already discussed that many times), but until today they at least claimed they want to hear from the community. You make it sound that they are now like EA and Co, want to stay in their distant castle without hearing anything their users want to say. Not sure if if it's your own idea, or that's how CDPR are actually now?
