> i do not understand "why" would a for-profit company like paypal or facebook would jump the bandwagon, build their own existing model of tracking and money movement with the poster of "crypto" and be like any other crypto model. Because money is a system of control. Even Bitcoin and other "decentralized" currencies are still systems of control, and the large Internet companies extract revenue from control, so of course they would want "in" on something they see potentially bypassing their controls over time. Why would they sit and watch this grow around them, or be beholden to existing legacy systems like SWIFT or credit cards, when they can potentially build something they are in complete control of instead. Ask yourself why governments reacted so harshly and swiftly against Diem, and you'll see how important a system of control money is.
