Re: game: redeclipse
Ugh, yet another game engine fork with other embedded code copies.
Doesn't look like the license gives us permission to recompress the
data and the redistribute that, "... redistribute or recompress...". I
would suggest you ask them to fix that since it seems pointless to be
able to recompress but not redistribute the result.
That whole section you quote is really in conflict with the claimed
zlib and CC-BY-SA licenses. Do they want it to be "open source" or
not????? Removing it might put the packages in main as long as the
license document you pointed to is accurate on the "all content ... is
"open source" friendly" point. I very much doubt that there is not a
bit of non-free code hiding somewhere. At the very least for it to go
into main, you will need to remove the logo: "[CC-BY-SA] ... does not
apply to the Red Eclipse logo", which is similar to what happened with
the Firefox/Iceweasel case.
The trademark bit is redundant, IIRC trademark law does not restrict
the activities allowed by that section.
