If it was Musk's intent (but I doubt it was the case, because it does not fit with a lot of other things that Musk did or said that show he is aiming at Faucci role in vaccine discussions), he should have acted to avoid poisoning the debate. There were plenty of "normal" way to do it, and in fact, other members of the Royal Society have done so and have expressed concerns when similar things have happened.

To me, it sounds like "Sure, Musk pooped in his hand and thrown it to the speaker during the conference, but the speaker made a sign mistake in their equation". If someone is saying that this attitude is awful, it does not mean that this person is pretending that the sign mistake did not occur and should not be corrected.
