Why do you believe that? It seems to me that the reputational damage caused by the U of C centre putting out bad slides is going to be stronger than any benefit they might get from being "seen to be a team player" or similar. Skepticism is always good but in this particular case, I do trust that evidence.

OK, but you can make the same argument for COVID. It seems to me that the slides are at least comparing apples with apples.
