"Who gets to be the centralized governors?"

In this case, Tron's management team (aka its board of directors), which is exactly how all publicly traded companies are run. Then if you do not like how the company is run, you have 2 choices: 1) Vote for a different board of directory at the next shareholders' meeting; or 2) Sell your shares. When the crypto industry is finally regulated (as it should be, and no doubt will be very soon), I suspect that is exactly how it too will be run.

I fully welcome regulation of the crypto industry. Only then will the fraud and corruption which now exists within the crypto industry be somewhat controlled. Sure, we may never fully get rid of it all, any more so than within the traditional markets, but at least regulation will be a very good start towards that end.
