commercial license to remove branding

Source-available rather than OSI-approved: a branding-retention clause caps free branding removal at 50 end-users per 30 days, above which an enterprise license or written permission is required. That charges for a class of use and fails the Open Source Definition, though the project is widely marketed as open source. Software that you can read but cannot freely run scores 2 on this scale.
