Because the identical logic works when used on athletes and musicians. You're just being obtuse and refusing to recognize it. I don't know if you get off on feeling superior to people who aren't developers, but I think it's weird you're trying to argue this angle so hard.
In all these professions, and many more, we're expected to maintain a certain level of performance (or capacity for performance) whether we're officially given the time for it at work and whether we're paid for it or not.
I also don't see how you can possibly in good faith compare "public performance" to whatever you think the equivalent "performance" is as a developer.
It sounds disrespectful and unnecessary, honestly.
