Even with Valve porting it's library over to Linux, the majority of total usage will still fall to Windows. The fps nuts and "I want to prove a point" people may switch but still, there will remain other games/software that will only run on Windows that will pull you back to that environment. The main reason they, those two companies, don't like Windows 8 is that Microsoft, in addition to maintaining it's own game studios, is now competing on the distribution front with a Store icon located on EVERY Windows 8/RT Start Screen. So, in all honesty, the Linux community can say "yay!" but really, they're the "guy on the side" that the wife used to make her husband jealous enough to make him want her again. So yes, be happy...because you're getting some attention, but just know...you're the cheap ho on the side. I primarily use Microsoft products but I do throw Linux into the mix often enough to like the platform but still, when these companies are bashing Microsoft and promoting your platform, they're not doing it because they're open source champions...they're doing it because they want to profit, compete and try to pressure their competitors. In the end, the Linux community still profits from the attention but the purists should understand the motives as the cheap ho's on the side get burned more often than not. In this case, you'll be promised attention and more than likely, eventually be let down by the lack of support that follows it. Hope for the best, plan for the worst.
