What if I take a Fedora DVD and sell it? (it was common for e.g. Debian CDs to be sold in the past, mostly before broadband was widespread; the Debian website even had links to such sellers). Wouldn't that infrige the MTP for the reasons explain in the article?
I also have trouble understanding how RPMs, both for Firefox itself and e.g. packaged extensions, fits the "you may not disable, modify or otherwise interfere with any installation mechanism contained in a Mozilla product" and associated restrictions. Maybe Fedora has written permission for this?
