What's needed to counter these is for customers to have their own contract of adhesion that simply says if the company is to accept them as a customer, then the company's own contract is null-and-void. This would be backed by a legal team in something like a customer's union or insurance that people would subscribe to for a monthly fee. This contract would be as enforceable (or not) as the company's, leveling the playing field. It would no longer matter what they put in their fine print since you wouldn't need to read it.

If a company doesn't accept the customer's contract or won't let you bypass their own, you walk away -- no sale. Other companies will get your business.
