It’s available; people just don’t know about it.
It doesn't even matter if POTS exists because it doesn't change the net neutrality problem. Dial up providers need to get access from the big networks. Those networks no longer have to follow net neutrality. So it doesn't matter if your local dial up company follows net neutrality because they must interconnect with Tier 1 ISP's that don't follow it.
Sure, but what’s the point?
The point is your claiming you canceled internet doesn't mean anything if you are using someone else's internet. It's like if you said, "I cancelled electricity to save the environment. I now run a power line from my neighbor who lets me use their electricity. I pay my neighbor instead of the power company." You haven't done anything.
Using the local library is paying for it. Your taxes are paying for it. You using more bandwidth at the library will cause the library to upgrade their service and pay more which you then pay with taxes. Net neutrality affects the library. You cancelling home service while still using the Internet hasn't done anything.
I would like to hear more detail about being unable to pay your tax bill offline
I might have been able to if I called the number and figured out what to do. But the default was "go to this url". A delay in payment means penalties.
Bus delay notifications sounds more like a convenience.
It used to be phone calls. It's not a convenience when the bus is cancelled and you need to know that you will need to drive you child into school. Sometimes the school itself is closed or delayed for a local reason that doesn't get reported on the news immediately like a power outage or plumbing. Grades are posted online. Schedules are posted online. There is no paper.
