It is possible to think anything. But that would be a very strange position to take. Bitcoin is pretty clearly the least likely cryptocurrency to be a scam.

I'm guessing if you are Amazon's size, you are thinking about doing (whatever FB's bundle of goods crypto was called) and doing it right. And skimming a percentage.

That is, a more centralized crypto that Amazon controls. Or at least one that has a known and stable conversion rate set by some entity (which could be Amazon) to other goods.
