The problem isn’t necessarily with the proposed ‘Net Neutrality’ regulations per se, but rather that the FCC wants to regulate the Internet like a public utility. They are merely using NN as the means to sneak the camel’s nose inside the the tent.
After they establish the precedent with NN, then the Feds can roll their sleeves up and really go to town. As public utilities, Comcast, TWC, etc., will be at the whim of the Feds just like any other public utility.
Expect to see the Fairness Doctrine resurrected (but not named as such), new anti-hate-speech regs, and other supressions of speech. Nothing is impossible at that point because they are now public utilities, so the First Amendment and other civil rights can now be trampled in the ‘public interest’.
Comcast and the Feds collude. They are in bed together.
