(Neither Shannon nor I actually work at Rancher/SUSE anymore, but) nothing has continued to (not) change here going on 8 years now.
There is still only one packaged version of Rancher; customers still run the same images anyone can otherwise download and use for free.
SUSE does not know or care if you’re in your basement, a fortune 500 company, or a government organization. They sell support services for people that want that.
All the code is still Apache licensed and you can still do anything you want with it (within the bounds of that very standard OSS license).
All of this applies to all the other Rancher projects that didn’t exist at the time this thread was created … Longhorn, RKE, k3s, Harvester, etc. (May not apply to every possible corner of the entirety of the SUSE org that bought us, I dunno.)
There is still no possible mechanism for any organization to enforce a guarantee that any of this stays that way. Forking the last version before such a change is still the remedy if that were to happen.
