Tbh it was never going to have as big of an effect as many made it out to. Net neutrality is very much a good thing since not enforcing it just fuels monopolies, but many places don't have strict net neutrality rules and the internet is still alive there.

Though, a big thing preventing this are anti monopoly laws - companies won't pay to restrict access to competition because all it would do is get them broken up. So the worst that happens is sometimes preferential treatment when it comes to data limits.
