Co-founded paypal so he like centralized financial system that is regulated and manipulated by private entities. He loves when people pays heavy fees on each transaction and people keep billions of dollar in their online payment account without getting any interest on it, those numbers are in billions. Imagine how much it will be in interest from billion dollar even when interest rate is low.

He might not make hate statement against bitcoin but for sure he dont like to support it because he havent thought of getting back to finance space anytime soon.
