Right, so in coming up with that interpretation you completely ignored the rest of the discussion and what the point of this question was. The point was not who the person asking was, or what their credentials were. The point was to figure out whether it was some external or internal force that prompted Elon to help. The status of the person who requested his help does not change whether he was the one who came up with the idea of helping or whether it was someone else who did.
That tweet might have motivated me to join the party, and I might even contribute to and be very welcome at that party, but to claim that I was invited to the party because some external force prompted me to go there is not common sense.
Or, you know, you could use try to be more sophisticated in your reasoning and realize it's completely possible and sane to have different criteria when evaluating whether Musk's decision to join a party in response to a stranger's suggestion was an act of hubris compared to when the event in question was an international rescue effort.
I would rather not claim more than I know, given that I don't know if he was asked officially.
