The Oculus Go was discontinued June 2020, the shop was locked down for any further updates or new games December 2020, that's just six months apart. They did "support" it with security updates until 2022, but it's pretty dead when no new games can be sold.

I used the correct dates, at least the text is copied/pasted from https://en.wikipedia.org/wiki/Oculus_Go

At least they released an update in 2021 that allows people to "root" the device so it won't rely on the cloud services anymore -- a pretty rare occurrence for abandoned products!
