> "GitHub wants to help developers choose an open source license for their source code."
This was built by GitHub Inc a very very long time ago.
So long ago, in fact, that it was five years before their acquisition by Microsoft.
The ones pushing for permissive licenses are rather companies like Apple, Android (and to some extent other parts of Google), Microsoft, Oracle. They want to push their proprietary stuff and one way to do that in the face of open source competition is by proprietary extensions.
The FOSS community at large embraced permissive licenses and it had nothing to do with the interests of big corporations.
And, sure, djb wasn't actually likely to sue you if you went ahead and distributed modified versions of his software... but no-one else was willing to take that risk, and it ended up killing qmail, djbdns, etc stone dead. His work ended up going to waste as a result.
I mean philosophically and morally, sure, one can take that position ... but copyright law does not work like that, at least not for anything published in the US after 1989 [1].
