In extreme cases, these restrictions may effectively render the program nonfree. It is unfair for someone to ask you to remove a trademark from modified code if that trademark is scattered all throughout the original source. As long as the practical requirements are reasonable, however, free system distributions may include these programs, either with or without the trademarks.
