IMO Steam is a glorified shopping cart that invades your PC and "manages" your purchases, they don't "own" anything, they are middlemen. I prefer to go directly to the vendor, if it's exclusive to steam I won't buy it because I refuse to install their malware gateway on my PCs. IMO the freemium model used by game studios such as wargaming.net is much more consumer friendly, just register, d/l, scan, hit install, and you done. From a business POV, wargaming.net has proved beyond doubt that a talented game studio combined with a player friendly freemium model can make you very rich, very quickly.
It's important that players who subscribe to a freemium game only gain a meta-game advantage, for example in WoT nothing you can buy in-game for real cash will give you a significant advantage on the battlefield. However a "wallet warrior" (me) will climb the tech/skill ladder ~1.5X faster than a "welfare warrior", a "wallet warrior" is able to extend the size of their garage/barracks, recycle expensive tank add-ons, paint their tank, etc.
Freemium models that significantly handicap a "welfare warriors" ability to compete with "wallet warriors" simply won't get enough players to attract a profitable community of paying customers, and the game will die. Note that the freemium model also applies to some traditional games (on a computer), such as internet bridge clubs who make money hosting tournaments, hosting bridge holidays on a cruise ship, selling/advertising advanced lessons, etc.
NVidia - I have found them to be a developer friendly company (CUDA, etc). NVidia have a large linux user community for scientific applications, their linux driver works, Yes, it would be nice if they could find a way to open source everything and there's no harm politely asking/reminding them, but hurling abuse at them for choosing not to is the act of a spoilt child. I for one, don't want OSS devs to be associated with spoilt children.
