nothing said about distributing it, although I see your point on the creation of it. But I'm not sure I'd be able to make that distinction about anything else valuable - "well, company x, you might 'own' this, but I created it and can do whatever I want with it". They want the benefits without any risks - ain't gonna happen.
Well... I say that, but I think everyone might have their price. I've got mine, and yes, sure, would I sign away all my IP created during employment for $x? yes, but no one has yet come close to that $x in job offers I get.
