Your typical cult is something fairly small, a congregation around one or a few literally insane persons which are indulging in short sighted self gratification such as convincing oneself that god speaks to them, or at times, around a person initially out for easy money (e.g. Keith Raniere).
The median cult may be small, but the median cult quickly dies. Why does this matter? If you were to apply your argument that cults are not intended to grow to, say, businesses, wouldn't it look completely ridiculous?
'Very few corporations are as successful as Microsoft. Your typical corporation is something fairly small, a group of one or two literally insanely optimistic entrepreneurs who are indulging in short-sighted egotistic expenditures such as the delusional belief that what the market needs is another Facebook clone, or at times, around a successful marketer out for easy money (e.g. Peter Pham). Said people need a certain number of close employees. Businesses are not intended to be successful or grow and make money, just keep loyal employees for the founder's gratification. The danger, likewise, is not in the successes but in failure modes that infrequently include mass murder like the Bhopal incident, and much more frequently include e.g. sexual abuse of minors, consequences to the customer's health, and so on.'
As I already said, cults die at such high rates that your theory is impossible because it presupposes utterly self-defeating behavior and is inconsistent with the behavior of successful cults.
Your reductio ad absurdam is something I can quite easily imagine Michael Vassar saying.
Some old SIAI work of mine. Researching this was very difficult because the relevant religious studies area, while apparently completely repudiating most public beliefs about the subject (eg. the effectiveness of brainwashing, how damaging cults are, how large they are, whether that’s even a meaningful category which can be distinguished from mainstream religions rather than a hidden inference - a claim, I will note, which is much more plausible when you consider how abusive Scientology is to its members as compared to how abusive the Catholic Church has been etc), prefer to publish their research in book form, which makes it very hard to review any of it. Some of the key citation were papers - but the cult panic was so long ago that most of them are not online or have been digitized! I recently added some cites and realized I had not touched the draft in a year; so while this collection of notes is not really up to my preferred standards, I’m simply posting it for what it’s worth. (One lesson to take away from this is that controlling uploaded human brains will not be nearly as simple & easy as applying classic ‘brainwashing’ strategies - because those don’t actually work.)
Reading through the literature and especially the law review articles (courts flirted disconcertingly much with licensing kidnapping and abandoning free speech), I was reminded very heavily - and not in a good way - of the War on Terror.
Old American POW studies:
Started the myth of effective brain-washing. But in practice, cult attrition rates are very high! (As makes sense: if cults did not have high attrition rates, they would long ago have dominated the world due to exponential growth.) This attrition claim is made all over the literature, with some example citations being:
