You've not just edit'ed and added to your comment, you removed a point about supporting open sourcing the games as a solution.

Many people (myself included) have absolutely no problem with that in principle. It's how do you do it that we have a problem with. Saying "just have every video game use the architecture that I have in my head that works, and isolate them from how all other software works" isn't practical.
