Don't I wish that were true. Off the top of my head, I know for a fact that a few of the Splinter Cell series games are impossible to run nowadays, and other games that used the same Ubi DRM too. And I just can't seem to get the original Fallout 3 working for either love or money.
As someone pointed out elsewhere in the discussion, app subscriptions mean DRM that's basically guaranteed to kill your ability to run the software once it gets old and everyone loses interest. If there aren't enough people buying old games for the publishers to keep them working, it's unlikely enough people would be willing to subscribe to make it worth their while maintaining the subscription processing.
