Yeah but at least you can get the games. On my old MacBook (my only "modern" Mac), Steam auto-updated itself to a version that no longer runs on that machine.

If that was my only computer (luckily it's not), I'd not only be completely locked out of the games I already installed, I'd also be unable to install any others -- despite the fact the games run perfectly on the machine. At least on GOG I can just go to the website and download the installers, no matter what [relatively-recent] computer I'm using.
