I mostly agree but I think the nuance with comedy is that there can be a mismatch in audiences, sometimes the others participating are not the intended audience, but are instead used as props. In that case it could be successful comedy independently of if they enjoyed it. Whether or not that’s ethical in a given situation is a separate question.
I think sometimes you get a mismatch between the audience the person thinks they have, and the audience they actually have.
For example, if you make a public post on social media, your actual audience is effectively the whole world. If you wanted a smaller audience, you should not have chosen a public post on social media as your venue.
