You can still purchase software on Steam, although the selection isn't great.

Wouldn't you say the Mac App Store and Windows Store are the "steam for computer programs"?

That's actually true, I never use them though.

I just hear so many horror stories about those stores (at least apple's store) like what OP posted.

Maybe just stay off the App store and do webapps if your app can run like that.
