Permissive licences require attribution. They clearly state that there have been cases where their code was published without attribution.

The only thing you ask with a permissive licence is attribution. Why would it not make sense to you that they want it honoured?

If they didn't even give attribution, why would we think they'd care about copyleft at all?

		In the permissive world, nobody cares about attribution. Many people actually don't even know that "permissive" doesn't mean "public domain". In the copyleft world, people are a lot more vocal. If you abuse a copyleft licence, chances are that some people will make noise :-).

Omitted attribution is of course a license violation, but their issues are not limited to just that case, and it's the other issues I'm addressing.
