Hi Liliana,
(I have no opinion about this topic.)
Your quote is:

but from the mentioned link [1], the quote includes a _but_:

If they
were licensed under the G P L it would fail the "preferred form of
modification" requirement, but its BSD-like license grants you all the
necessary rights to modify, use and distribute them.
.
While there likely was, once upon a time, a custom set of tools to create this
game data, those tools do not exist any more. The original creators of the
game are in the same situation as Debian's users when it comes to
modifications.
.
Also, the reason for requiring the "preferred form for modification" is to not
put the creator of the software/data in a "monopoly" situation. This isn't the
case here.

My understanding of the Debian argument is:
1. the licence is BSD-like respecting the Debian Free Software Guidelines
2. point #3 of DFSG [2] says «The license must allow modifications and
derived works, and must allow them to be distributed under the same
terms as the license of the original software.»
3. considering game data, all people are equals – from original author
to users – because the tool set for modifying these game data does not
exist anymore
Therefore, drascula is part of the ’main’ Debian archive, scummvm too.
Tobias wrote [3]:
Either the inclusion of [a subset of] Drascula in Trisquel[0] is
a similar oversight, or we're missing some legal subtlety.
so maybe some legal subtlety is indeed missed. Let wait an answer by
FSF licensing department… if any. :-)
