After not even hearing the words for well over 3 years, today I was faced with no less than two prospective NDA's to sign. I haven't yet.
Reading over the one I did get sent to me, I am struck by how... inhuman... it is. Essentially, the NDA says "We, Corporation X, are interested in shoving some data into your CPU and RAM, but by no means may you add this data to your memory, at least not for five years."
In other words, in exchange for the chance to make some money, I relinquish my "self" and serve as a dummy processor.
This makes me uneasy in the extreme. The cost of doing business is relinquishment of self.
I left the corporate world over this. I think I may turn down two very lucrative contracts over it as well.
