The ISPs would not support it. They would take the levy and find some clever loophole to steal it or to use it to reinforce their own walled gardens.

You're talking about possibly the scummiest, least moral companies in the global tech industry.

LARGE ISPs. The small ones are fighting tooth and nail to survive and bring the local people better internet. It has to be folly to be in it for the money at many local scales unfortunately. Thats why I get one choice of 2mb internet here. There are local guys working out of a pickup truck laying copper and fiber to local business. #notallisps
