The author put it well:

What if you have petabytes of data? How do you backup a backup? What happens when that backup contains HIPAA-protected information or client data? The whole promise of cloud computing collapses into complexity.

Multi-region cloud computing is already difficult and expensive enough, multi-cloud is not only technically complex but financially and legally fraught with uncertainties. At that point you're giving up so much of the promise of cloud computing that you might as well rent rack space somewhere, install bare-metal infra, and pay someone to drive there to manually backup to tape every 3 months.

This level of technical purity is economically unfeasible for virtually everyone, that's the whole point of paying a vendor to deal with it for us. And you know who doesn't need to put up with the insane overhead of multi-cloud setups? That's right, Amazon, Microsoft, and Google, who will be getting paid for hosting everyone else's multi-cloud setups while they get to run their huge infra on their own cloud without fear. The last thing GAFAM competitors - especially OSS projects - need is even fewer economies of scale.

Stop with the victim-blaming, this blunder is squarely on AWS.
