i'm glad someone pointed this out. 

when licenses like this come up, the question we have always used to
decide if it is DFSG is "is it a request, or is it mandatory".

if the license only *requests* something (please send me a postcard, or
a six-pack of beers, or please donate to my favourite charity) then it
is DFSG free.

if the license *requires* that postcard or beer or sexual activity then it
is not DfSG free.
