They usually don't make sense optimizing before achieving these levels of expenses. I mean, for a really long time the expenses are so low that it would cost more to engineer these solutions in the first place, and then they suddenly run through the roof exponentially.

But mainly, priorities and "it's not that much in comparison to all else". And perhaps not even tracking the costs properly :)

I see the practical angle but I still don’t get why companies are so happy to park their private internal data in S3.

They have that much faith that the world’s biggest target will never be hacked nor hire a dishonest admin?

It doesn't feel unlikely they would be ordered by a government to share data too.
