you don't know that. you don't know what economic or social reasons they have to stay in CA. It really isn't fair to ask someone to quite their job, leave their friends and family, and move somewhere else to protect their privacy.

Yes but all those words you just wrote apply just as well to a corporation. (Employment or use of products)

There is a difference between moving to a different state and using a different product, but I see your point.
