most billionaires are to ego drive to stay quiet, Thiel is the only one that does it simply because hes also gay, and doesnt want to face the wrath of the anti-gay conservatives. thats why he always is very secretive, remember his YOUNG MALE BF/boy toy he drove him to his death recently(theres some suspicion he may have had a hand in it) and not a word from the media, except maybe 1-2 articles over it.
