How do you know Monero is actually private?

Before anyone comments the obvious, yes, I know why it is private. My actual question is; how do we know it wasn’t created by the FBI (or similar agency)

If you think that is a little farfetched, let me point you towards the ANOM app. An app used by people doing huge drug operations that they were convinced was anonymous. Not small time criminals either; we are talking in the millions.

So back to my question. What if the FBI was actually running monero, and using it to catch big money launderers in the future? Would also explain why there is such a big reward for anyone who can crack it. That is there as a red herring.

Anyway that is my conspiracy theory, thanks for reading.

Edited to add: imagine you found a privacy/security vulnerability in monero. Would you tell everyone? Or would you collect the reward?

Edit 2 to say this was a post to take a break from the constant ‘are we in bear market’ posts. Don’t be too harsh in my DMs guys
