Never implied he was "trapped", but he was clearly goaded . Did you watch the interview with the diver? He very much unnecessarily belittled Elon's efforts to help save the kids. Everyone was trying to save trapped kids and there was no need for anyone to attack anyone else's efforts (this includes Elon). I'm sad Elon was so easily goaded into that snap reply, I wish he was smarter than that—but it turns out he's a fallible human after all.
