I have a similar anecdote. I work for a company selling a recommendation platform to travel agencies, and the content we display is often similar in layout to regulars ads. It happens, from time to time, to demo a version of their own website to them, with the proper recommendation block injected (mostly to seek the client's validation on the look and feel). And, I recall having one of them congratulate us for the fast loading and clean display of their pages (on my ublock-running-browser). I didn't pick this up. Obviously, the original page was literally cluttered with ads..
