Re: "Having given the world our software on the most liberal of terms..."
That's rather a lot of downvotes for:
1) A statement of fact, that the GPL is intentionally illiberal, in that it forces contributors to redistribute under the same terms, with no value judgement on this fact
2) A statement of opinion, that commercial open source developers today probably prefer Apache/MIT for its simplicity and compatibility with *aaS business practises (cf. VMWare's woes).
Neither of which strike me as particularly controversial. I guess the FOSS crowd just are irrationally angry sometimes.
