I disagree.. playing a guitar does make one a musician, and writing does make one a writer. What either is not entitled to is success in the marketplace, but then, no one is, regardless of skill. Once you put your work into the marketplace, the market decides its value, and your value by proxy. But for that to work successfully, the marketplace has to efficiently sort for quality, and one way to enforce quality is having the barriers to entry be sufficiently high. In practice, that doesn't often work because entrants don't want to be sorted efficiently, they want to be sorted to the top to maximize exposure and revenue. It's why SEO exists - to optimize the Googlebot for you and you alone by any means necessary. Unfortunately, Steam also wants to maximize the size of its library and revenue, so it has an incentive to engineer a marketplace that favors quantity over quality.

But even amateurs put in more effort than the developers publishing much of the garbage onto Steam - using the term "developers" loosely. These are incoherent rage games or weekend projects, barely functional tech demos and tutorial games, asset flips, etc. Games that don't even run. If the bar for quality on Steam was merely "amateur" then I would be happy, but it isn't. There seems to be no bar, and that makes it bad for everyone, except maybe Valve.
