It’s all anecdotal but in my experiences it’s usually opposite. Bored senior engineer wants to use something new and picks a AWS bespoke service for a new project.

I am sure it happens a multitude of ways but I have never seen the case you are describing.

I’ve seen your case more than the ransom scenario too. But also even more often: early-to-mid-career dev saw a cloud pattern trending online, heard it was a new “best practice,” and so needed to find a way to move their company to using it.
