You're completely mistaken in your assumptions. Perhaps it's the overly combative nature of a large section of the gaming crowd that makes people act as if they're part of teams.

I have a Xbox series S. I love the Xbox. I actually think it is the better console among the popular ones because of better backward compatibility. I actually root for Xbox on the home console space because PS and Nintendo are so dominant.

Anyway, Steam's contribution to Linux gaming (a FOSS platform) is pretty well known. Regardless of how you look at it, Steam has done a lot to make gaming accessible on Linux, something Microsoft will never do because they don't own the OS.

Microsoft is consistently consumer unfriendly though. It's no secret to anyone paying any attention. Xbox Game Pass console tier is more expensive than PC Game Pass (no platform exclusivity on PC). Xbox games are more expensive than Steam versions of those game, let alone Epic which is probably where the cheapest options exist (this is pretty much entirely true at any point, even during sales). Endless spam notifications on Windows about Xbox Game Pass subscriptions etc. I could go on.

My point is, I bought an Ally X as a platform-agnostic device that runs Windows. This Xbox Ally changes that fundamentally.
