alt Hacker NewsIIRC the reason they abandoned Oculus brand was that Palmer Luckey sold the company with condition the Oculus headsets would not need a facebook account to use it. Later they renamed the company and headset, and would you look at that — it requires meta account now.
I think the Oculus Quest 2 was the first one to release with a Facebook requirement, but it was still Oculus-branded. It was this headset that they swapped out the branding on when they renamed themselves to Meta. Earlier models still have the Oculus logo on them and the controllers, despite being as locked-down as all the others. The rebrand came much later than the account requirement.
