I see most SaaS the same way. Often (I'd go as far as saying usually) it is not what customers want, it is what vendors can push on them to get recurring revenue.

Also it's not gonna work for fast-paced games without turning those games into the stupidest skinnerboxes at some level behind the scenes. In order to make it possible to send precalculated results for latency hiding, a lot of freedom needs to go.
