I'm not sure if anyone is interested, but the game mentioned in that article is now for sale on GOG.com . It was released earlier today. Its currently on sale for 50% off for the next week.
The unfortuante truth is that Steam is more or less the 'benevolent dictator' on the PC gaming side. Not being on Steam is pretty much a death sentence for sales. Note that Steam could have been like a walmart, crushing distributors to their whim. So far they've been mostly kind to devs, and despite their problems, are by and large a benefit to the PC gaming scene, more than they are a hinderance.
Note though that at the end of the day, Steam doesn't have anything that can't be replicated by others. Just like devs are now moving from GFWL to Steamworks. If the gaming landscape changes, developers can switch away from Steam to other platforms as well. Unlike Walmart, they don't control the last mile to consumers, and thus are in a lot more of a precarious situation than other 'monopolies'
