I don't get it. What's the point of your post? You don't think there's any value in sharing how they did it? You really think they might bet copied and eventually failed because they shared their stories on HN or something?
There is great value in it. Greater still for the wrong people.

I don't 'think' this, I know this for a fact, I've seen it 3 times up close now. And I fully expect there to be a fourth within a week, see the current HN homepage.
I personally find valuable to see examples of people next to me who managed to succeed. It means to me that it could not just be a dream.
