Are you going to start with that BS? Why as soon somebody has some success, everyone start talking about conspiration Theories? WHY?

In his previous post, @RetiredCoder mentioned having 20 RTX 4090 GPUs and claimed to have used the kangaroo algorithm to solve the puzzle.
He mention that he use his own optimized kangaroo version, so what we can deduce from this is that the JeanLucPons kangaroo's version wasn't enough efficient as expected.
Go ahead and look at his optimised Kangaroo then.
