That’s true of pretty much any App Store that isn’t strictly invitation only. If you have an app follows Apple’s rules, it gets listed. Whereas Steam, by comparison, exercises editorial control over all of its content. The solution for a better Mac App Store would require Apple to be similarly dictatorial about content.

In that sense I agree with you; personally I think it was a mistake of Apple to have the Mac App Store so closely mirror the iOS App Store. They should have made it a more aggressively curated experience.
