Marius, if I understand correctly, you have summarized your patch with respect to the following two issues:
1. Your patch strips out parts of Chromium that are /clearly/ nonfree and proprietary (e.g. unrar per your example), and 2. Your patch addresses (or tries to) privacy concerns. But as far as I can tell, you have not addressed the concerns shared by Bill and others about the situation with files in the Chromium codebase that don’t have a clear license. So I’ll try to repeat/rephrase their question(s): does your patch address the files with unclear license? Does it strip out those files that don’t have a clear license? Can we be certain that the Chromium built from your patch explicitly *only* contained free software? Best, amin
