I've brought this up as the "child porn" clause, and had brought it up in an employment contract once many years ago. Basic language was "we own anything you create". I said "I don't really think you want that - if I create some child porn, you're the owners". I seem to remember I had some less restrictive language placed in my contract vs that one, but I don't think it made a change to anyone else's contracts. Yes,…
IANAL , but I believe in this case the offence would be in the creation and distribution of this content not necessarily in owning the IP. Otherwise you could technically make the same argument about instagram for example.
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.
