The crux of the argument is summed up in these two, scant sentences; "would that mean that some games might not make it to Steam? Possibly, but that's OK." This is pure NIMBY (Not In My Back Yard) rhetoric, except these people have absolutely no skin the game in any sense. So, perhaps it's more like, Not In Your Back Yard rhetoric.

I honestly don't understand why it's so hard for people to just ignore crap games and go on with their lives. There's tons of crap restaurants I don't go to, crap beers I don't drink, crap TV shows I don't watch, etc. I don't go around telling my corner store to stop carrying Bud Light because I think it sucks. I don't go over to the property owner of the nearby Pizza Hut and tell them to lease to another restaurant that I prefer nor do I go to that Pizza Hut and tell them what kind of pizzas to make. Similarly, these people should not be going around and telling video game retailers what they cannot sell, simply because the consumer-in-asking wants a hugbox that suits their purchasing preferences.

By all means, voice your opinions. I might tell my corner store that I don't really like Bud Light and would prefer they stock more beer from Stone Brewery. It's up to that store to decide if they want to or not. And they can actually do both, allowing me to enjoy Arrogant Bastard while others can still enjoy Bud Light. It's an expansion of choice, which is good for both industry and for consumers, whereas the opposite of that is the restriction of choice as dictated by the most vocal. Furthermore, it's astoundingly arrogant of me to say that they need to stop selling Bud Light because it's not as good as other beers. These facets should be blatantly self-evident and the latter is largely considered to be the antithesis of consumer choice and freedom. Ironically, one of the biggest proponents of this kind of anti-consumer rhetoric is Totalbiscuit, who constantly touts himself as being pro-consumer.

It makes me wonder how in the world this kind of mindset became commonplace, let alone acceptable, although i largely suspect its due to an echo-chamber effect of fans of personalities that espouse this rhetoric. This kind of consumer-policing is obnoxious and self-righteous, ultimately not really doing much to benefit the consumer, but doing a lot to advance a narrowed vision or idealization. It's fine if you don't like RPG Maker games. I don't either. I also don't like H1Z1 and DayZ, but I don't care that they're sold on Steam right along with RPG Maker games. I ignore them and buy the stuff that I do want. What a crazy idea!?

And lets be absolutely clear: people selling games on Steam that you don't like is not limiting your access to the games that you do like. I also find the basis for the claim; that there is cognitive burden due to the extensive amount of choice, to be absolutely facetious. How many people actually make purchases by browsing through random games on Steam? The vast majority buy games based upon word-of-mouth, advertising, press coverage, a known IP, a known developer, etc. Having an unknown developer dump a ton of obscure, low-tier RPG Maker games on Steam doesn't make Skyrim and Dark Souls hard to find, and it doesn't mean that games like Overcooked are overshadowed. It's an absurd and blatantly false premise that is being used as a foundation for a fundamentally flawed argument that holds no weight.

Last of all, Gabe Newell has repeatedly said that he wants all games to be able to be sold on Steam. There's some obvious exceptions within that (porn games, games with malware, games that abuse Steam's marketing systems, etc.), but barring some pretty obvious caveats, Gabe wants nearly anyone who want to sell a game on Steam to be able to do so. And I agree with that. It's economic Darwinism and , much like evolutionary Darwinism, holds up pretty well for being self-correcting and for positively advancing markets.

TLD;DR - this article can be summed up as, "I only want Steam to sell games that I (or a selective group) deem worthy," which is a bigoted and selfish view that runs counter-current to everything that we know about best managing markets and providing consumer benefit.
