Lol. You're just going to ignore Tencent, founder of QQ, and countless other older, proven-to-be successful tech companies that aren't from anywhere near Beijing?

Being nearer the beauracracy never helps your flexibility. It helps your funding for development of things that are of interest to the state.
National government, sorry.
