It happens quite often around here. I post something about what Gerald or Geraldine Guru says about fill in nutrition topic du jour, and more often than not I get at least one comment notifying me that Gerry has changed his/her stance on said topic. I'm then told that it is the mark of a thoughtful and serious person, as they have changed their position based on new information. If this were the case, I would agree. But more often than not, this is not new information ... outside of their world.
The sad reality in this greater community is that the demographic most influenced by Gary Taubes was not scientists (thankfully) or the medical community (sadly, some have been), but the guru community. They picked up and ran (and boy did they run!) with TWICHOO. And make no mistake, many in the paleo/primal community were heavily influenced by this and seemingly did not engage in any independent, critical thinking, let alone research of their own prior to writing their own various books.
