Well, there’s the ALFIS project

MS Outlook is the joke.

And it’s still entirely unrelated to my point, since SUSE will remain the trademark in question regardless of what’s actually contained in OpenSUSE.

But yes, the free/open-source spins of things tend to have somewhat differing content compared to the commercial offering, usually for licensing or support reasons.
E.g. CentOS (when it still was a real thing)/AlmaLinux/etc supporting hardware that regular RHEL has dropped support for, while also not distributing core RedHat components like the subscription manager.

Not at all what my point was. There’s indeed plenty of Open-something (or Libre-something) projects under the sun, but no free/open spins of commercial projects named simply “Open<Trademarked company name / commercial offering>”.

To be fair, OpenSUSE is the only project with a name like that, so it makes some sense that they’d want it changed.
There’s no OpenRedHat, no OpenNovell, no OpenLinspire, etc.
