There are some toll roads in Canada - and even at least one that is operated privately if I recall.
Would you allow the toll agent on such a road to look inside your vehicle and ask you your ultimate destination, even if that destination was somewhere well off the road you were on at the time, and then base the toll you paid or even if you could drive on the road on the information gained from looking and asking?
I sure wouldn't - but that is what Canadian ISPs are trying to do, and the Canadian Government through the auspices of the CRTC may just let them do it.
Would you allow a private toll road to your home to be operated in such a fashion that goods and services you want from someone other than the owner of the road were charged exorbitant tolls, but the road owner's own goods and services got a free pass? The CRTC here in Canada has just allowed the incumbent (and dominant) ISPs to do exactly that.
Personally, I (almost) find this an excellent reason for the public to take over the creation of and management of the digital highway system - and I'm not only generally anti-government's involvement in business, but one of the founders of the commercial internet business in Canada. Here's why I feel this way.
Note that I'm NOT in favour of government having the ability or the right to shut down such a system as Egypt's government has done in recent (late January, 2011) days. Somewhere between the extremes of business walled gardens and bureaucratic strangling there has to be a reasonable balance.
