Eliminating net neutrality incentivizes ISPs to build auxiliary services that they can artificially support by throttling the bandwidth of competing products. It incentivizes them to seek profit by favoring some net traffic over other net traffic. It does not in any way incentivize them to build larger or better networks. It does not incentivize them to invest in their infrastructure. All it does is let them make mor…
Business Model 1: Build your own services and throttle everyone else's services unless they pay a premium (in which case your own services would be cheaper, but the profit they get from their own services must be higher than the profit they get from NOT selling the bandwidth their premium service uses, to third parties). Let's put it this way, if a hotel builds a Jacuzzi, you're argument is that the hotel owner will…
There are two reasons they would do that.
The first is price discrimination. Suppose Spotify makes $2/month worth of profit but uses $0.05/month in bandwidth. Now Verizon can charge them $2/month for that amount of bandwidth and take their entire margin. Even if Spotify nominally continues to exist, they now have no margins to reinvest or use to attract new private investment, so they're walking dead. Which harms customers because now Spotify can never improve their service. And if Verizon does have a competing service (see also: TV and phone) then Verizon's service gets an insurmountable competitive advantage.
Which leads to the second reason, which is to extract monopoly rents. Suppose Spotify charges $10/month because they have competitors, so they can't charge more without losing business. But if they had no competitors then they could charge $25/month. Which means that Verizon can charge $25/month if they can get rid of all the competitors, which they can do by just charging them all unsustainably high data prices.
Hotels can't do this because hotels have real competition.
