Engagement is an easily-gamed metric that (in the absence of heavy gaming) usually vaguely reflects satisfaction, addiction and usefulness. Gaming for engagement is unethical in the general case, but I suspect this specific instance is leaning towards “satisfaction” / enjoyment, rather than addiction. (I'm not certain, though; I don't understand the (para)social dynamics well.)

Yes. Do you want the person to quit his job over it? Unless he's the C+ i'm sure he doesnt have a say in the ethics of the company.

Why? We're democratizing attention a little bit. I don't see why A-listers should get all the attention.

What conversation could this person possibly have on a take like this? So what if the answer was simply “Yes.”
