But should they really? Because I am completely with you in that this is increasingly problematic in a world where certain services are so core to our lives, taking part is increasingly unavoidable and being shut out is actullay a disturbance to ones social or economic life. Considering how lopsided the power balance is, I do not think it is okay for companies to be allowed to in essence randomly terminate accounts and services that are vital for other businesses or private people to function, no matter what is stated in the ToS.
