ISP: Here's a cheap IoT plan! $5 a year! Customer: Yay I'll buy a ${Brand} IoT device. ... Customer: ISP, why isn't my {$Brand} IoT device working on your network?

Fundamentally, ISPs are already charging the most money they can get away with at this point and time. The law doesn't change that, and net neutrality doesn't restrict that. They like money, so they set their prices as high as possible. The only thing net neutrality laws prevent is cheaper, limited internet plans BELOW that. For smaller things, low income families, etc.
