C: brainwashed and having a placebo effect
Final answer.
Actually, the 90s were a low point for the organization in a lot of ways. They could no longer charge money for literature due to a court decision, funds were drying up, the move to softcover books was initiated, there was no slick media like today, even the quality media they had like the org video and convention dramas took a nosedive in production value over that decade, and probably most important, one of the biggest teachings they had for decades, "this generation", had to be changed out of necessity. Only those so far in they couldn't see the forest for the trees wouldn't notice.
