Regarding your title question, the last major one got torpedoed by Microsoft, then sold to Taiwan. Regarding your point about regulations, I can't quickly Google up anything on this, but I was under the impression that China was supporting the USB-C convergence in their internal market, and was going further to encourage the vendors to converge their various "fast-charge" standards. Generally, regulations like this help everyone but powerful incumbents, so they're not really that political in most places.
