Amazon CEO Jeff Bezos on Tuesday said, "Seek revenge, and you shall dig two graves, one for yourself," on the ongoing tussle between Gawker Media and PayPal Co-Founder Peter Thiel. "If you absolutely can't tolerate critics...then don't do anything new or interesting," Bezos added. Thiel is backing wrestler Hulk Hogan's lawsuit against Gawker Media for making Hogan's sex tape public.
