This is ultimately what it comes down to. Contracts between very rich/powerful entities and relatively poor/powerless entities, in practice, can contain anything the rich/powerful entity wants because the poor/powerless entity cannot afford litigation. Cell phone contracts, car leases, employment agreements, basically anything written by a company and targeting an individual--just read one of them. All the clauses protect and benefit the company, and very little good is in there for the individual. And they are take-it-or-leave-it: There's generally no negotiation or ability to add individual-favoring terms [1]. Try negotiating the legal terms in your cable bill and let me know how that worked out for you. Contracts among equals tend to be more fair because each side is on a level playing field.
