With the caveat I'm technical not legal... Its largely kept data caps off domestic lines, but not entirely. Net neutrality has had a couple taking points and its a long fight at the FCC that's gotten weirder by the decade.

Net neutral meant Microsoft couldn't make the MSN dial up network prefer windows network traffic, over the years companies got smart and just opted to pay for peering instead of running the low profit access tunnel.

Google even drops boxes to cache stuff at tiny ISPs/WISPs, but doesn't deprioritize traffic to other end points.

There have been intermittent swings at labeling this the pay to play it is, but since the investment isn't spilling out of public works there's a decent case this is the fastest you could give out access to everyone.

Companies are going to be slow to adopt to these kind of changes when there's a possibility that they'll get changed back again in a few years
