It does store data so it is a data structure. Every implementation is meant to store data and the whole point is to have more memory locality so how it stores data is actually crucial.
No, not every ECS implementation is about data storage (to be more precise, component storage). This architecture's abstraction being better suited for data locality is the main appeal, yes, but many appreciate the mere separation of the GameComponent's Components into Components and Systems. So your assertion about it being strictly meant for data storage is just wrong. As [2] states:
> Data is often stored in cache-friendly ways which benefits performance.
Notice it says often, not always.
And bear in mind, generally, data structures aren't just about storing data. They are about storing data in a very particular way.
> That's data, so it stores data, so it's data structure.
Technically, the component storage is, at best, a ADS. But that's grasping at straws given that you can just store components directly in a function's stack frame. Still, the component storage isn't "the ECS" in the same way that a service injector isn't "the Clean Architecture ", even though you'll always have them in some form in each.

Now, where did I say that?

For the discussion of whether ECS is a data structure, it is, given that you previously stated that ECS was meant for storing data, and "often" contradicts that.

I haven't asserted anything about it. You did, and you have yet to prove it.

Pretty much everything stores data in someway. Which brings us back to the "kernel is a data structure in your eyes?" question from earlier. I don't think it is me who isn't making much of a point.
No one knows or cares about whatever "ADS" is, injector services or 'clean architecture'. It seems like you're caught up in so much nonsense that you don't think that a class meant to store data is a data structure.
