They're transitioning to a model where customers curate everything for them. We're in a weird in-between spot now I guess, but in the end no one is telling you to buy crappy unfinished games. If you do that then it's pretty much your fault, no? Especially since every game has endless coverage on youtube and the like.
Someday when there are user stores and such, and I can go to the RPG Codex store and see all the decent Western RPG games in one place, that will be awesome. That's Newell's goal. We're just in a transitioning period at the moment on the way there.
Zurvan7: Don't care really, at the end it's just video games. Won't be the end of the world if steam shuts down. As long as they upload a patch that will remove the steam DRM. (which they've said millions of times they will if something ever goes wrong).
I think they said it once, and it was in a totally non-binding way. This idea they have promised that is total fantasy, honestly. In fact the Steam terms of service say the exact opposite, that they can shut down and take away your games at any time for any reason.
