Cannot this be a method to take money out from company? I.e. Slack as a company pays $50M/year and Amazon pays back 20% of this as a "reward"?

At such scale it should be easier to have its own infrastructure rather than pay Amazon's overpriced bills.

Theoretically any payment can be. That’s why we have corporate auditors, money laundering and financial investigators, etc.

I doubt Jeff Bezos is running some slush fund laundering scheme.
