Unless it's able to be tied back to being a Linux purchase in some useful manner (like Id, Epic, and S2 have...) you're NOT buying a Linux title- PERIOD. When you buy it (downloading is merely getting what you're paying for...) and it's not a Linux title in some manner, you're sending votes for the OS that it was written and sold for. Complaining doesn't matter one whit unless you're talking half or more of their customer base bitching about it.
Just want to know your opinion on this. Sorry if it's already written somewhere.
