I'd argue that Zuckerberg was elected. People voted by signing up for his website and using it regularly because it was better than the alternatives at the time.

People are free to stop using facebook and move to a different site, as many have. This only requires a few clicks.

I overwhelmingly prefer the option of having many companies to choose from vs. having the government or laws determine what is truth. Switching governments often requires either a revolution or a decade-long immigration process.
