At the far end of this reasoning three separate companies that all use AWS share the same underlying infrastructure and all go down when AWS does. It doesn't mean they're not independently managed.

And the same could be said for the electrical grid, the post services, roads, etc. I agree that infrastructure and monopoly are two very distict concepts.

But there aren't 3 different Amazon marketplaces--owned by Amazon--built on that infra. And AWS is available standalone.

Here we have core infrastructure that isn't sold to anyone else and powering 3 supposedly different social messaging services.

The key isn't the backend, it's the supposed independence of the frontends.

No, it’s relatively easy to go from one cloud platform to the other (thanks god for terraform). To go out of fb infra? I can’t even imagine.
