I'll call this a Carrot Problem.Once you look for Carrot Problems, you see them everywhere. Essentially, any time someone achieves success in a way they don't want to admit publicly, they have to come up with an excuse for their abilities. And that means misleading a bunch of people into (potentially) wasting their time, or worse.

For example:

People who take steroids don't generally admit to taking steroids, so they come up with various explanations for their new physiques. But anyone who follows that advice will be disappointed; without the steroids, they just won't get the same results.
Many companies basically distribute their jobs to friends and insiders, but don't want to admit that publicly. So they set up public application processes, which cause outsiders to waste time and effort applying through a channel that has 0 chance of landing them the job.
Various companies make a lot of money by implementing "dark patterns", such as getting customers onto subscriptions and then making it hard for them to cancel. They can't admit that this is why their revenue went up, so they make a bunch of claims about how their success comes out of [various beneficent strategies], but anyone who tries to replicate the success by using those lovely strategies is liable to go broke.
