The frustrating part is that these posts will never post any details about the business, despite the fact that it would immediately invalidate most criticism.

It seems to be a similar phenomenon to productivity "gurus" who write and evangelize polyphasic sleep and "grindset" and so on - when you ask what they're using these superpowers to actually accomplish, they're very quiet. Or it's "coming soon." Or "I'm not going to waste time explaining to someone who obviously doesn't ~believe~." It quickly becomes religious.
