>>20752183It forces people who link to any software under the GPL license to change to a GPL or GPL-compatible license. It's advertised as "Free as in freedom" but it's more restrictive many other choices of free software license. This wouldn't be a problem if it wasn't the one that the creator of it, who is also the founder of the Free Software Foundation and GNU, suggested that everyone use as a free software license.
LGPL would be better than that. It still has copyleft but doesn't have that clause I mentioned above (although it's not a problem since the game is not a library, using the GPL would still promote that horrible license)
