I see that you're not of high opinion of fame and the famous ones.
WIth great power comes great responsibility. Yao Ming has used his fame to help reduce the demand for shark fin soup in China, and that caused a substantial decrease in the number of sharks killed each year purely for their fins Celebrity used responsibly. Then comes the example of basically every other famous person that exists.
Alright. PewDiePie helped raise a million dollars for various charities, which may or may not include his "Charity: Water" campaign raising more than $440k. I don't see how does it relate to privacy concerns for famous people. You can't look at extraordinary examples and say "Oh, this is what everyone whose name is on air should do!". We're all human beings. Some of us can do great things. Most of us are only capable of good ones.
