Confirmation bias is a tricky beast...

Even if Ct values are unchanged between vaccinated and unvaccinated cases, this is conditioned on being infected in the first place, and isn't the whole story. Duration of infectiousness matters.

Yes, boosters are necessary to reduce infection with Omicron, the antibodies from the original vaccine are just too big of a mismatch. That's not news. I'm glad to hear you're not taking those negative efficacy estimates at face value - it's almost certainly the result of missing confounders present at the start of their omicron wave. Unvaccinated individuals are probably less likely to live in urban areas, travel internationally, or even seek a covid test, for example.
