A lot of domains are taken over by disruptive force controlled by networks of people rather than single entities and it’s just waiting to happen to the cellphone industry. In US the operators have control over who can send SMS on the network they even control who can route calls to them and use this power to block VoIP users.
However – it seems that the inevitable change to this is coming – Truphone has recently got a court order that T-Mobile has to stop blocking their calls… Seems like even the mammoths of telecom will need to budge.
I think this is typical to what any industry will have to face as the power moves from huge corporations to smaller startups, communities of users and products that doesn’t need as much anymore to be created and spread.
