This licensing page appears to be a new addition to TfL, which probably suggests some bureaucrat negotiated a deal with a creative agency to license the tube map for pennies on the dollar, resulting in them sending out these notices.
Amusingly the notice was sent with references to USA trademark law.
I am not sure how it works with regional governments, but copyright information for government-produced works tends to live as a "crown copyright" in the UK and former colonies.
