Are you talking about a mobile phone data plan, or a hardwired ISP-ish data plan? I'm about 99% sure that the specific classification this fight was over only applied to the latter, not the former -- there was never any "neutrality" in this sense for mobile data.
Both, to varying degrees. And of course carriers are going to tailor their cell gear to their benefit in ways unknowable to customers without enterprising investigators conducting some seriously-dedicated SDR packet capturing and N carrier x M handsets x P locations x Q time-of-day testing. 0. Even assuming lossless/infinite backhaul capacity, it gets messy when guessing about what's deployed in terms of packet prior…
I think one of the primary tasks of proper pricing is to recover costs of deployment and maintenance, isn't it ? Deployment and maintenance aren't free you and can't ignore those costs. Providers must build those in both to recover past costs and to build a reserve for future deployment. It makes sense that those who need more bandwidth should pay more. This emcourages more bandwidth to be deployed. The more deployment the more supply. The more supply comes on line, the quicker prices go down (or depending on demand, the slower the price increase). This has been so clearly seen in gas prices, where price caps have never worked except to choke supplies and artificially pump up denand. Allow prices to float freely according to use, and prices go up if demand goes up. Higher prices encourage suppliers to bring more online, and/or discourage inefficient uses (gas guzzling vehicles) and prices go down. Price caps always distort markets. Net neutrality functions as a price cap that slows deployment of more bandwidth, increases inefficient use, leading to slow internet for all greatly impeding innovation
