Actually, some universities are rather protective of how businesses use their symbols. I can name one: Texas Tech University. When I left there a few months ago, they were just beginning a campaign to reign in local merchants' use of their name and logos. The idea being not so much to stop them from using the symbols, but to make merchants license the "officially sanctioned" versions of the the university seal or the "Double-T," and to do away with embarrassingly bad home-brew signs and such.
