> a private corporation taking the source to make a commercial project and refusing to give anything back (whether patches, money, or otherwise) is abusing.

What I'm saying is that's the point of the license. That's why universities use the licenses (e.g. MIT, Berkeley) and why Apache uses it. They're designed to stimulate the private sector by moving IP from research into industry (universities) or by industries pooling resources to make software purchases cheaper (Apache).

I don't think it makes sense to describe using them in this way as abusive or bad faith.
