Non-bad companies could set up "will not get bought by Facebook" poison pills. Say they will release all IP to the public domain when acquired by Facebook. Enforceable contract with a third party.
I'm tired of reading these type of comments. Do you enjoy VR? Just create a facebook account, that's not a big deal. There's nothing evil there, people are just grasping for straws.
I deleted my FB account over 5 years ago. A few years after that, I tried creating a new one to sell something on Marketplace, and they closed my account, saying I needed to provide a driver's license due to fraud. I'm not giving FB my driver's license to sell something online, and I'm certainly not going to do it to play a video game in VR.
if you're a seller I'd imagine you have to give a form of ID yes, as a buyer they have pretty much all my information from credit card to address of residence.
If I ever move my racing sim rig to VR, it's definitely not going to be an Oculus.
