Going beyond that, they typically have a monopoly or duopoly as an ISP, while they're subject to competition as a TV provider.
Much of net neutrality can be reduced to "don't let monopoly ISPs leverage that into a monopoly in other services".
If Verizon didn't offer TV, this wouldn't really be a problem. If there were 17 other broadband ISPs to choose from, this wouldn't really be a problem. But Verizon does offer TV and they're one of two choices for me and most of their other customers, so it's a problem.
