Could have handled it gracefully by saying their crack team of experts did the best with the information that was relayed to them and it's a shame some want to turn a good will gesture into something it's not.
Instead he gets triggered like some Evilore butthurt, tries to sound like he played a more important role in the whole thing by saying 'well I never saw him there' as if the guy wasn't significant to the operation, slanders the guy as a pedo and more egregiously makes a claim he'll film his sub getting all the way to cave 5—as if enough lives haven't been seriously endangered in these caves already—just to score internet points.
There's no chance anyone is risking their lives for this guy to prove some point, let alone on a sub that very likely can't maneuver through the cave system. Musk pls.
