The author of this article reflexively and illogically defends Steam (like usual):

But at least some of what Kaldaien complains about isn't necessarily on Steam's shoulders. It's well within devs' powers to provide players with access to older game versions on Steam (KOTOR 2, which I recently replayed, lets you access its pre-Aspyr version via a beta branch, for instance), but many of them elect not to. That strikes me as an issue with individual devs rather than Steam as a whole, and as for Steam Input? Well, again, if there's a problem there it's with developers electing to use that API over OS-native ones that's the issue.

He literally completely misses the modder's point. Steam itself will not run on the original machine you purchased KOTOR 2 on. You can buy a gaming machine, purchase a game through steam and 6 years later, one random day you're suddenly no longer able to play your game, simply because Valve has decided that the version of Steam that you bought the game through is no longer ok and now you need to upgrade your hardware and OS to play the same game you've been playing for years.
