And then separate from that, the core of the 2012 court decision was the 2009 "legal protection of computer programs" directive. But in 2014 (in the Nintendo vs. PC Box case) the CJEU basically ended up ruling that games did not fall under that directive due to how heavy they are on non-software (audio-visual) content[1].
I'd be really curious why Valve's lawyers ignored these avenues and went for the ridiculous subscription option. (And equally, I'm curious about why France was going after Valve when PSN, Xbox Live, Apple App Store and Nintendo eShop appear to be softer targets).
