I like Wolfire. Their head (David Rosen) had a really good procedural animation talk at GDC about a decade ago, their games are pretty good, and they started up Humble before it spun off on its own.
Before tarnishing their reputation, I'd suggest reading up on the actual complaints put forth in the lawsuit. I've done so extensively, I think they have very solid grounds to go after Valve (Valve's behaviour is comparable to Amazon's in terms of anticompetitive practices).
I haven't read it either. There is however a If Books Could Kill episode about it that is very worth listening to.
