Meta will delete all non-migrated Oculus accounts in March - The Verge
(www.theverge.com)
This is a most excellent place for technology news and articles.
And the time before that, when Meta claimed you would not need a Meta/Facebook account at all and could continue using your old Oculus account. They reneged on that within about a year, from what I recall. Sources on that are tough to find because they've been trampled by the more recent bait-and-switch, and subsequently this one.
Long story short, Meta has now lied three times about the ongoing account requirements to continue to use the hardware you've already paid for, pulling the rug out from users contradicting what they said before.
