> Looking at his track record, he got fired from Zip2 and PayPal
Technically, no, he got fired as CEO from X.com twice, once before it had PayPal as a product, once after it bought Confinity which had PayPal as a product. X.com became PayPal right after the second time he was fired, so he never actually got fired from (or worked for) PayPal.
He was also fired from Zip2, which was a separate company. You are technically correct that PayPal at the time was called X.com, but it's still the same company.
