The DFSG refers to copyright licensing, it doesn't cover patents or
trademarks. The difference between trademarks and copyright, is that
copyright covers all copies and derivatives, while trademarks cover
anything that's confusingly similar. So if you independently create a
logo that looks confusingly similar, you need a trademark license but
not a copyright license; while if you create a derived works that's not
similar at all, you need a copyright license, but not a trademark license.

Having a restrictive trademark license prevents people from using
confusingly similar logos, while a DFSG-free copyright license allows
people to make derivatives as long as they're not confusingly similar.
