there are lots of streaming services who compete with pay TV
This is exactly the problem. When the ISP, i.e. Comcast/Verizon, has it's own streaming services, it's a conflict of interest for them to be 'competing' with Netflix. They can, and have, used their monopoly position as the ISP to prevent quality access to Netflix by the ISP customers.
You think that Netflix is getting 'free' internet access? They are simply responding to MY request to stream the content to me. Netflix pays they're ISP to get on the internet to provide content just as I pay my ISP to get on the internet to consume that content. Comcast/Verizon sold me a service at a certain speed/bandwidth and if they can't provide those speeds, it is their problem when people try to start using those advertized and sold speed/bandwidth.
since the FCC wouldn't have to undo several decade-old orders that classified broadband as an "information" service rather than telecommunications
But that's the problem. They are telecommunications services and not fixing that bad decision is just lipstick on a pig.
the longer they run the bigger that decommissioning fund grows.
Sort of the same way pensions work right? Unless you're company decides to raid the pension for short term financial issues and goes bankrupt...
Claiming that the original estimates didn't include inflation is a a minimum disingenuous at best and dishonest at worst. Do you have any evidence to support that claim?
Did new developments change the costs? I have no doubt they did, but it's better to learn from history than to repeat it...
