I think companies that have sufficiently significant market capture should be laden with a "universal service obligation" as an antitrust-type measure. They shouldn't be able to refuse service unless they can prove the customer is doing something illegal. If they do refuse service, the customer should have grounds to sue them to restore service. This might go against some people's idea of a free market. I think it should only apply where there isn't a free market - when a customer doesn't have many other options, such as in the case of Google or Apple, or Visa/Mastercard, a major supermarket, or the choice of cellphone provider or Internet provider in markets where there are only a few options. It wouldn't apply to small independent traders by definition. Capture enough of the market where there isn't enough competition and you get obligations to treat them fairly.
