The Walled Garden, The Internet Gate
When you connect to any provider, you begin in a (fire)walled garden. Within the garden, providers can compete by providing proprietary content, tunes, movies, news, whatever.
This garden will usually also feature gates to additional features and services, for example a back-net credit card processing gateway, the PSTN (public switched telephone network,) Internet (r) brand connection to the network of networks, KidSafe (tm) brand filtered network connection, if they can think of it, they can offer it.
So long as there is clear disclosure, they should be allowed to offer, or not offer, whatever they choose. But if a provider chooses to use the Internet Brand Name for one of their gates, then they should be required to meet net neutrality rules.
Consumers should be able to choose the features and speeds they want, and access the provider with any legal device they select.
