It doesn't even have to be in companies that big. The AWS salespeople took the CTO and a couple of directors of engineering for diner in a fancy restaurant. That was in a fintech that had around 200 employees. AWS also paid for the mandatory marketing... sorry, mandatory training sessions we tech managers had to do.

This is how much it takes for a CTO to demand the next week that "everything should be done with AWS cloud-native stuff if possible".
