I think this is a classic market failure due to network effects/monopoly; one of those cases that could be resolved(?) by looking at the earnings of the company in question. Are they making a loss. Break even. Small profit. Large profit? If, after all the creative accounting, they still show a large profit then it certainly must be a monopoly. Otherwise someone else would come in and offer the same service for less.
