Caprices of TOS details, reviews, algorithms, service quality, or whatever are not the real problem. The real problem is when you can't reasonably choose to do business with someone else and move on, as they are free to do with you.
Network effects are causing more and more important things to both expand into great significance and to be dominated by a single company (or pair of gatekeepers, both of whom must be appeased, as in the phone platform.) Your business can be utterly wiped out with no realistic recourse by any of a thousand actions that could be taken at any time by the giant, like an elephant stepping on an ant.
I'm afraid that the only real recourse is to have certain anticompetitive regulations automatically kick in once a business rises above a certain percentage control of access to some market or medium that has become significant. They lose the ability to unilaterally ban, for example, except in narrow cases involving fraud or suspected criminal activity, which will eventually have to be proved to some official. If they fail to prove it, the official will order compensation without the banned party having to fight the giant's lawyers.
