One of the barriers I have observed in several legislative bodies, including the U.S. Congress, is an unexpected lack of faith in their own (legislators') competence to make sound judgements about "technology."
They frequently seem captured by jargon, and mermerized by minutiae, such that they take whatever the "experts" tell them and go with that.
This has allowed major tech companies to basically run the table on getting public policy rules and attitudes that favour them. The impact is rather dramatic. For example the entire discussion about competition law reform has been routed to arguments about controlling the search market or controlling the advertising market. It has been completely deflected from far more fundamental questions such as the infection of oligarhic structures in Western eonomies that stifles competition and throttles true inovation.
Just consider the role of the key cell phone players. If they were in the business of making houses how long do you think it would take for legislators to act if the house maker told homeowners they could only buy furniture from approved sellers? That they could only subscribe to electricity from an approved power vendor? That all of your activity in your home becomes the property of the house builder for purposes of "improving future houses, marketing, and improving our business." No one would stand for it.
Now apply that to the wide ranger of oligarchies in our economies. Amazon is both the "franchisor" and its own franchise actively selling against its victim-franchises. It provides a market place for a fee, effectively charging for the privilege of letting them take your customers. Cable and telco companies are not only carriers, they create and own content, and they actively put up barriers for other carriers to offer such content in any way that is not exactly in the interests of the carrier-content-owner.
This has been a problem in other industries but always it was pretty clearly a bought legislature. Today politicians often quite sincerely think the whole thing is over their own heads. I know this because I have dealt with a lot of them in varying capacities. One, in response to a Standing Committee investigation of Google's opposition to a Privacy Commissioner's findings, sponteously spouted, "Well, after all, privacy is really dead anyway isn't it?" Realizing he spoke out loud he leaned back in his green chair and gazed blankly at the ceiling.
@Ted Wrigley is large right, in my view, but I think it is more severe. The lack of informed thinking, willingness, or capacity to act by politicians is compounded by the active disinterest of voters. By this I mean their disinterest is much deeper than mere apathy. When told by their various providers that what they are getting is possibly threatened by a government initiative, the user-victims of the oligarchs will actually become intransigent about doing nothing. Kind of, "Why should I care as long as I can Facetime with my boy friend?"
