You realize that 'control' does not mean 'regulated by', it means that they actually control it. Color me shocked that yet again you don't even understand the definitions you are linking to and then try to call me a liar when I expose your ignorance.
You better go edit Wikipedia and bring it up to snuff, btw. First, their definition seems to be way off (despite citing your same source!):
Second, as for the ACA:

Those sloppy editors left it out there too. Seems like you have a lot of work to do. Maybe they are in on the eskimospy conspiracy though.
You appear to be confusing regulatory authority with nationalization, which can be a common mistake. If you would like to learn more about what nationalization actually is, here's a quick couple of paragraph primer for you.
