sure, but think of this.. Most people will say that listening in to a phone conversation is 'spying' and not right, and, it turns out that listening is hard, due to poor connections, accents and other noisey issues. BUT at scale, simply collecting and mapping the patterns of connection/duration over time is much more informative than most people imagine, and few object to that. Surprise.

Run the scenario you describe, and people being intrusive, rent-collecting bullies that they can be, and do you think the sole-sourcing of "giants" will be a tame and orderly affair ?

There are two directions to take that thought at least.. one is, what did previous groups do in past times that did create positive results; and second, a tech games-theory approach to de-centralization mixed with special purpose business entities, with real checks and balances.

Personally, I assume that business cannot be trusted over time to keep the consumer of services best result in mind.
