There is some truth to it. Everyone wants a developer with extensive public portfolio (github/stack overflow/open source contributions) and ideally great performance with algorithmic brain teasers, but don't realize that such people are quite literally celebrities. Do you really need George Clooney for your soap opera? Is the budget of your soap opera sufficient to hire George Clooney? Another thing - for the dirty stuff the celebrity will need a double;)
