commercial license to remove branding

A branding-retention clause caps free removal of Open WebUI's branding at 50 end-users per 30 days, above which an enterprise license or written permission is required, so the license fails the Open Source Definition despite its BSD-3-Clause origins. Open WebUI is widely marketed as open source, but that use restriction makes it source-available rather than open source.
