When Facebook (NASDAQ: FB) acquired Oculus for $3 billion in 2014, the company made some promises to the company's founders and users. The biggest one Oculus founder Luckey Palmer highlighted was that he was promised by Facebook that users wouldn't need a Facebook account to use the Oculus Rift (the online headset in development at the time).
Palmer is long gone from Facebook, and any promises the company made about requiring Facebook accounts are gone too. Like it or not, Facebook is in full control of Oculus.
