Data isn't code. OpenOffice doesn't force you to licence everything you
write under the GPL, and the free versions of Quake can load proprietary
game files without there being a legal problem.
So FlightFear's reluctance doesn't have a sound basis.

It's not about the project or the community, it's about the individual
users.
If ActiveState's users aren't free to use the software, the health of "the
community" is a distraction from the lack of freedom of individuals.

If people won't research or ask about the problems and won't accept the
answers there's not a lot that can be done.
In the case of BY-SA, the issues that there are are well known and easily
explained. The big one being that BY-SA don't apply to data or the database
right. ;-)
Flight simulators or startups are not the problem, and will not have a
problem, unless they have been poorly advised elsewhere or they are trying
to get around the licence for some reason that they are not stating.
