If they don't get new guest accounts, they're all going to shut down withing 30 days. It's just left over accounts and caches giving you the impression everything is fine.
Don't forget the rolling DoS herds of scrapers having no more ways to do stuff on their own, which are now trying to use the remaining instances - killing even more.

The upgrade path for keycloak is also similarly broken in my experience. Especially the total change in one of the recent versions broke a lot of things, which they are still fixing. Add no visible LTS or security patching on top, and you end up with something, that isn't usable for any enterprise rollout.
Compared to when I lived in Zurich essentially all government officials were willing to even just entirely speak English after briefly suggesting we speak German and only rolling their eyes slightly that I wasn't competently able to. Navigating the system there as a "first year resident" was zero problem by comparison.
