Surely you're not suggesting that anybody besides you understands the differences between any of these 30 open source licenses. I've been writing software professionally for 15 years and I can quote you the initials of a few of them, but not even the names. I honestly don't have a clue as to the contents of those licenses, and I just plain don't care.

Sure I've contributed a fair pile of open source software. But it's just code that I've put out on the internet, with no silly license attached. It's entirely possible that some of the places I've stuck that code have presented me a list of checkboxes to randomly select a license, so one of them probably got checked. I can't quite understand why anybody takes this stuff seriously enough to spend even 5 minutes comparing licenses.
