The LICENSE[0] doesn't say that. That's merely Open WebUI's interpretation of their own license. Now, a judge would probably consider that estoppel, but you don't want to rely on that.

Using the license on its own, you effectively are saying:

- Don't use our branding to endorse your fork

- Don't remove our branding from your fork

The only way to satisfy both of these is to not fork.

Also, they forgot to reformat the new clauses for 80 column text, which makes the license unreadable on the normal GitHub viewer.

Ugh, that's a real mess - they've clearly just invented their own clauses and tacked them on to the end of the previous 3 clause BSD license.

Technically, they're allowed to do that - the BSD-3 license is itself public domain - but it's usually a pretty bad idea. Have the new clauses been written by a copyright lawyer, or at least been vetted by one?

The fact that this is Open WebUI's second license change this year should be a red flag for anyone considering contributing to or relying on their software.
