This comes down to the old debate over which philosophical framework is the basis for ethics and morality.
If you’re a deontologist, you might say that Mr. Beast is not a good person because he intentionally exploits people when he provides medical care for someone, by uploading their reactions for engagement.
However, a consequentialist would say that the outcome is more important; the means by which people receive medical care is irrelevant, and in this case, their treatment essentially necessitates compensation via engagement.
