In reply to Carl Hancock.

In regards to the source code instances, how does CentOS (before it was bought by RedHat) handle it? To me, that would be a better vector than Firefox/Ice Weasle since RHES is GPL v2 and Firefox has its own license.

I can see removing references to the comments, branding and other information, but I'm unsure if there is any established case-law on trademark for a name in a call or function. In that case, I'd also have to assume that there was a trademark for all parts of the name (all capitalizations and spacings). Moreover, if the function call is something like wp_migrate and not wp_migrate_pro_db, I'd argue that the trademark wouldn't even apply unless there was a separate trademark for wp_migrate (which frankly, I'd hope wouldn't be granted because that is incredibly vague, plenty of people could "infringe" without even knowing it).
