I've really started to take a disliking to Valve in the past few months. First were the Steamworks exclusive games which isn't horrible, but I don't like games being exclusive to one DD provider. Next, they decided to trademark 'DotA' and take claim to a fan project that tons of people worked on (I know that Icefrog works with Valve now, but they should make their own IP instead of riding off something that already exists and would create a legal nightmare), and now the whole TF2 microtransaction debacle.
