Does anyone else remember the "PayPal Mafia" article (http://fortune.com/2007/11/13/paypal-mafia/) that Fortune did some years ago? There was one description that really stuck with me -- how customer service complaints were handled under Thiel's watch:

Customer-service complaints flooded the phone lines and in-boxes and were often dealt with by simply not answering the phone or doing a mass deletion.

What sort of leader treats customers like that, or looks the other way when minions do it?

There was also the ugly Facebook ownership shuffle when Thiel got involved as an early investor and a lawsuit over Thiel and his hedge fund management company (http://www.law360.com/articles/9340/paypal-cofounder-accused...).

For Thiel to lecture Silicon Valley about ethics is a bit rich.
