A closer analogy would be that you asked the house cleaner to clean the pool house when you actually needed the main house cleaned. The house cleaner recognized that you asked for the wrong area to be cleaned, but went ahead and did it anyway, but did a great job cleaning the wrong thing.

The cleaner isn't the problem with respect to the cleaning itself, but what about the culpability in exploiting someone who has lost their mind? In this case Zuckerberg is willing to accept the exploitation that occurred in the past simply for what it is, but now that he has had a moment of clarity he also cannot let it continue.
