The sentence is worded a little confusingly, but my interpretation of it is that for certain companies, since Amazon is a competitor in the business domain of that company, AWS is a nonstarter even if it's product offerings are a better choice. Walmart is the canonical example.

I worked for a company where this exact thing happened, for this exact reason.

I no longer work there, but they chose GCP because AWS wasn't even in the running because of this.
