This kind of comment is remarkably shitty. Someone performs the extremely unpleasant and stressful task of publicly admitting to his mistakes so the rest of us can learn from them, and xcubed responds by spitting in his face. What's the result going to be if we tolerate this sort of behavior? Well we don't have to guess, it was documented in the original post: most founders are not willing to admit their mistakes in…
When someone does a bunch of shitty things that directly affects the lives of others, anger is a wholly reasonable response. While it's nice that the OP is being open about mistakes, you don't deserve a pat on the back for telling the truth, it's the default behavior we expect of people.
There are obviously different scales of truth-telling and deception. "It's your baby." is a lot different than, "Ah - I can't make it. I'm just too tired!" But it's still lying. In fact human lying is so frequent that a lot of the smaller lies we tell to be polite or avoid hurting feelings barely even register as lies, even though that's what they are, plain and simple. Clearly Kant's maxim that lying is permissible under no circumstances is false.
In business lying is rampant. You are competing with liars. Marketing is institutionalized lying. People are constantly embellishing the features of their product so that it purports to do something magical when on closer inspection most features are much more mundane. Sales is even more about convincing the person you're talking to that they can't live without something they probably can live without. In other words, being a good liar is pretty much a qualification for the position.
Does that make it ok? No. But does it mean our expectations are lowered? Yes. So when someone goes out of their way to come clean and tell the truth at great disadvantage to themselves, especially in business, we should recognize that for the exceptional event that it is. I don't think that makes lying more acceptable - but it incentivizes truth-telling.
