This appears to be a hasty conclusion. Older people with paxlovid did equally well as younger people without paxlovid. That indicates that paxlovid actually works, given that older age leads to covid mortality! The author's only refutation of this is that the same pattern was observed before Paxlovid was around. But that pattern itself is an aberration that is not true of the general population, it's only true in that one geographical area due to, I would assume, a statistical anomaly.
