Yeah of course, I'm not saying the contract wouldn't have an influence on my actions, just that I don't (and you shouldn't) feel a moral/ethical obligation to follow it.
And that's exactly what those contracts are aiming for: not to control your mind, but to establish a deterrent from much more nefarious shenanigans, if thoughts of such shenanigans arise. Some of the top Silicon Valley companies (dating all the way back to the 70's) would simply not exist if those contracts were followed to the letter.
