I think it's safe to say that, during the first couple of weeks after it emerged, a majority of people who disliked the endings did support the indoctrination theory. Then they started to move past the knee-jerk "anything's got to be better than this" reaction and actually look at the details, and that eventually led to today's situation where it's only believed by a dwindling core of diehard, cult-like kooks.

But it was pretty popular at the beginning, at least among people who disliked the endings.
