I wonder what fraction of homes don't load anything from AWS on a daily basis. I suspect it's way below 50%.

(Of course, they don't know they're using it, they're using a service on it)

And utilities are typically natural monopolies. They're good candidates for regulation because they're essentials and they don't have competitive forces to keep them behaving reasonably.

AWS has plentiful competitors. If you don't like their behavior, don't patronize them!
