I expect common carriers to have a duty to neutrality and defer to at least some government agency with oversight before deciding to pull the plug.

There is one rail line to carry grain in and out of a community. That rail line is a common carrier. It shouldn't be able to arbitrarily decide whose cargo to carry or not.

There is realistically only one ISP at my home. That should be a common carrier. They shouldn't be able to arbitrarily choose which IP addresses I can connect to or not, or what ports I can choose to talk on. I realistically have no choice on who to choose for that, so there's no market for alternative providers for me.

AWS is not a common carrier. If you get dropped from AWS there's still Google Cloud, Azure, Oracle Cloud, IBM/Softlayer, Hertzner, Digital Ocean, Linode, Hostgator, Dreamhost, and so many other smaller cloud/VPS providers out there. And that's assuming you're for some reason entirely unable to roll your own hardware and move your app into a colo, of which there are literally hundreds of providers in the US alone. There is lots of competition in the cloud hosting industry, and if you widen it to the hosting industry in general its extremely wide.
