That argument is completely unrelated.
If they were publishing "Elon has flown X miles, used Y fuel and created Z emissions in the past T time" that would be far different than what they do.
You are reaching for excuses that can't possibly apply. Perhaps you should ask why you'd go so far to excuse this doxxing, but not others.
I personally dislike Musk and view him as a conman. I take issue with several things he's done at Twitter and even more with what he's done at companies like Boring Company, Paypal, or Tesla (eg, promising the first car to the actual founder then launching it into space just to spite them).
People here just managed to find a thing where he happens to be right (whether it comes from personal pettiness or actual principle).
If Elon is concerned maybe he could just rent a jet as needed instead of keeping one all to himself.
