Why does it matter where regionally the pool's owner is based?
Almost every major pool has multiple instances spread across the world to lower stales. Even if the owners are in China, the miners themselves are globally distributed.
It is pretty trivial to setup a pool these days - so in the event that one of the Chinese ones were shut down, it'd be easy to setup a pool in another region.
The matter is how the pools are run, the high fees, and where the profits are going. Right now China dominates Bitcoin mining and this lack of competition affects all miners that aren't in a position to reliably solo mine.
Did not create this thread to start a philosophical debate though, interested in feedback on what feature(s) would motivate you to switch from your current pool.
