Look at the history of it’s core product to see where VR will go if it takes off:
Facebook was the cool place for college students to connect with friends. No ID requirements to sign up and no ads for years. Your feed was just your friends post. Things were great. Now there’s ads in your feed and you need to definitively prove your identity. Not to mention the history of scandals and privacy violations.
They’ll do whatever it takes to get those first 100 million users. Once they get them though all bets are off. Privacy will only get worse, they’ll give up on the initial power users because who cares about a couple million hard core gamers?
