>That harm and those people are apparently not as important as some business goal. That offends me.
I understand your point.
> Why would an insult convey more offense than all the criticism in the article already does?
That really depends on the aim of the article. If it is to express a feeling, fine, she did express her feeling. If it is to make a point, she shouldn't, or one might simply say she cannot have a rational discussion, because it simply doesn't prove anything. Google didn't use insult, it undisclosed private information. While it is senseless, it's not an offense, in the sense that there's no proof that it was intended to hurt. I don't believe that S. Brin woke up one day with the idea of harming people, or do you think that is what happened? If it were the case: if I had been the victim of a deliberate attempt at hurting me by disclosing things about me that I consider private, I would be seriously pissed. The question is: was it deliberate, or was it simply an error, or a misunderstanding? People make mistakes, that's unfortunate, but it's understandable. She, otoh, cursed voluntarily.
> It's also a particularly harmless insult that as far as I can tell
That's anyone's appreciation. In a different culture, it might well be the worse thing you could say to someone. The fact that it carry already a insulting connotation is enough: there's no way someone could take it as a compliment, thus whether it is harmless or the worse one could say is besides the point, the message is clear.
> That's a lot of words about this sidetrack
For a minor issue, that happened in _the title_, but I surely don't care that much.
