The problem is that anger often sounds more authentic but anyone who has ever been angry will testify that what you say when you're angry (or even just irritated) doesn't necessarily reflect your actual view, just one facet of it.
Yegge's original piece was making a specific point and he came out with examples that supported that but that doesn't mean that those examples represent Yegge's overall view of Bezos and it's reasonable that he might want to throw out the other side of it.
In terms of whether it's honest - from both pieces I think it's fairly clear that Yegge doesn't believe that Bezos gives a shit what Yegge thinks so I see no reason why Yegge wouldn't be being truthful.
But even if Yegge was toning himself down, I don't have an issue with that.
I think that among some in the tech community there is a feeling that "honesty" and "truth" tend to trump everything. While that's great in theory the baggage (usually personal offence) that comes with it has to be considered.
Ultimately life is about getting stuff done and for most of us who aren't Jobs or Bezos level genius where brutal honesty will be forgiven, a "polished" truth will often get us better responses from others than it's more brutal counterpart.
If that's the case we all have to ask ourselves do you want to be right, or do you want to get things done?
Note: I'm not talking about lying here, I'm just talking about how you present the truth.
