This is confusing to me. Rather than one or two good, open, reference implementations everyone uses you'd rather have multiple proprietary solutions? That seems worse for people who want to learn from a commons of knowledge and hugely inefficient and a waste of time. I can see an argument for copyleft style licenses for this stuff (though I fundamentally disagree with them, freedom based on copyright that requires police and courts to enforce isn't free) but you appear to be arguing for completely closed solutions, though I assume I'm misunderstanding?
