> Extreme case: google, does not use aws for its main load; this upper threshold I wager is couple of orders of magnitude smaller
Not a good example in my opinion, as Google is also a major provider of cloud services. AWS isn't the only game in town.
I think Disney+ is a more interesting case. A quick google search turns up some articles saying their video streaming is powered by external CDNs. As I understand it, Netflix take the opposite approach and deliver all video data from their own Open Connect CDN, although they use AWS for other workloads (presumably including things like authentication, their recommendation engine, etc).
