I think you're reading too much into it. If China does standardize on a Ubuntu derived distro with their own specs and it gets released for public use (and by that, offices both private and government sector will also begin using it with government taking precedence due to the ruling party influence), that by default causes it to be pushed as the standard in homes as well. You wouldn't want to keep disparate OSes around; it's just too much of a hassle for most folks.

"Force" in that context means proliferation by standardization at work, trickling down to home, not in terms of "use this or else..."

Now I don't know to what degree console adoption fares in China, but if it's high enough, PC gaming won't deter enough users to prevent it actually becoming a viable alternative on par with Windows at some point.
