Actually, we don't have "net neutrality" since ISPs can prioritize traffic.
What you may be thinking of is US oversight over ICANN (who assigns IP numbers and manages the DNS), which has kept the infrastructure supporting the free flow of information generally free of government control. Actually, the current administration was planning to cede US control over ICANN later this year, but Congress pushed forward a 2-year extension in the December budget bill. The concern is that if the US doesn't oversee ICANN, then countries like China will want to impose direct controls over the internet (right now they need to employ a massive national firewall).
They can now. Up until recently, the FCC had it set so that ISPs were forbidden from prioritizing traffic, but never officially classified them as a utility. Rather, they were information service, as they're currently classified as now.
This is ultimately what tripped up the works, and lead to the hooplah we're now deeply involved in. Apparently, when it comes to legal matters, you have to call a spade a spade, rather than an onion to make it kosher. Information services aren't beholden to nearly as many restrictions as utilities are, and it was thus illegal to hold them accountable as such. Someone sued, can't remember who, and now we're having this discussion.
The important thing to remember is that while there is no restriction on ISPs prioritizing traffic, we've effectively been functioning in a net neutrality-like environment since the 90's at least.

If the telecom companies won't tolerate VPNs being legal, what makes you think that they will tolerate the net-neutrality laws that you are in favour of?
They don't. Haven't you seen the advertisements? Read the reports? Seen the astroturfing? Comcast, Verizon, and Co. are very much against Net Neutrality.
