But okay, lets go with the distributions desire to chose what license to use. Who cares about the license? The whole point of pragmatism winning over idealism is to achieve a set of practical effects, regardless lofty concept such as "freedom of choosing license".
A distribution is most effective when it can use the best software as much as it can. This mean that a pragmatic distribution should use any software, be that proprietary, GPL, permissive, anything, so long it is superior. A pragmatic approach to license issues would be to have built in tools to slim down the distribution to reach specific practical effects depending on the need of each individual users.
Surely, giving people working graphic drivers is more pragmatic than giving people nothing and say "the software that give your practical use from your hardware is under the wrong license".
