it's related. ISPs and telecom in the US do not invest adequately in infrastructure, and the existing infrastructure is overloaded. net neutrality was all about how that infrastructure can be utilized; ISPs want to profit off the scarcity by allowing big companies to pay for priority so that their website would load faster at the expense of everyone else (big companies want this too, and they want it to be expensive, because that increases barrier for entry in a competitive space where they already have an upper hand), but the net neutrality laws used to prevent this sort of bidding for priority.
some ISPs also wanted to sell "internet lite" packages that are cheaper and only allow you to connect to a fixed set of websites. presumably they would also take money off the back end from those websites that want to be in the list.
