I know. That's why Amazon is better positioned. They at least own the upstream infrastructure. Netflix is utterly dependent on three other industries, but is itself pretty easily replaceable. The had a first mover advantage in getting favorable content licensing deals before anyone thought it would matter, but that's fading fast as those deals are renegotiated. And its value add is totally fungible. People care about the content and will happily use another provider if they have the content. Netflix' foray into original content is an existential move.
Except it's not really that dependent on Amazon - there are nearly perfect substitutes for every AWS service.
Comcast is different because it already operates as a monopoly in many areas, and it's trying to change the rules so that it can leverage that monopoly, to the detriment of everyone but themselves, and there's not really anything that anyone but the regulators can do about it.
