Assuming that ')copyright' works in their copy of FriCAS I think that
they are covered from legal side (IANAL). And assuming that they keep
normal FriCAS banner (identifying binary as FriCAS and giving info about
')copyright') that looks more or less OK.
Concerning bug fixes and patches, in relative terms we got infintely
more from Sage folks, but contribution from Sage folks is rather
small part of overall contributions to FriCAS. So I am not
surprised that there are no visible conftibution from Mathcad.
