Do these Indiehackers stories ever leave out important details?

(Example: I remember reading about ProSoundEffects in a book, and the author (Tim Ferris) left out important facts, like how the founder of the company had years of experience in contract law and negotiated exclusive distributorship deals before automating the business in Yahoo Stores. In other HN anecdotes, people leave out all the spam and email ads they have to send in order to get sales for their product.)

And I think it's fine, as long as it gives something valuable to the readers. Not necessarily repeatable business ideas (there's a saying that when someone share his secret, it's already exhausted), but it gives motivation.

That's the whole point. You thought the founders were getting warm fuzzies from sharing their story?
