Just curious, how on earth did Kevin and Amir get such incredibly detailed of AWS spending of these accounts.

Either they put it together from public resources, or (more worrysome) someone at AWS leaked them line-item based expenses of their top customers.

This has got to be incredibly sensitive data for AWS, not something they'd want leaked. If I'm (say) AirBnB or Snap, I'd worry that this data leaks information that would be detrimental to their ability to negotiate for cloud computing with Google, Microsoft etc.
