That's the decade old philosophical fight about what to consider free software. GPL/GNU vs BSD. I think both opinions are fine, if you don't want your contributions to end up in a commercial product, you can't contribute to a project with BSD/MIT license. On the other hand most companies prefer to support projects with a permissive license over projects with copyleft (GPL). For many projects (except the big ones like GNU/Linux) copyleft seems to be more of a burden.
