>Oh, and reading and understanding licenses is HARD?!?!? WTF?

Hey, man, you know what? Some people want absolutely nothing to do with legal/compliance folk in large bureaucratic companies. Not that they aren't lovely people, but that involving them in your work is more risk/work than it's personally worth.

>but really, at no time in the 90's and 00's did you think it may be worth some time?

Hearkening back to the 90's and 00's, I'd venture to guess that there may have been some amount NIH syndrome at MS with respect to OSS, in addition to uncertainty as to how future inevitable licensing problems would be resolved in courts.
