If you're engaged in a voluntary business relationship with a corporation, they're going to have their own terms, reasonable or not. And yes, the more asymmetric the relationship, the less reasonable the terms.

Fortunately, working for any particular corporation is voluntary. And thankfully, it seems that sunlight has disinfected these specific extreme practices. Hadn't heard of either.
