You're incorrect on all three counts.

I never claimed he copied code line by line, and that issue was never litigated. I never even sued Mark. So I definitely didn't "los[e] that one in court."

Anti-trust scholars and Congress agree that Facebook has a monopoly and has engaged in monopolistic behavior. See https://judiciary.house.gov/online-platforms-and-market-powe.... It's an open question as to whether the FTC will sue on these grounds.

You don't provide any justification at all for your assertion regarding a lack of Ponzi-type behavior, so I'll just note that I disagree.
