At Google she had excelled at selling online advertisements and growing Google into a cash gushing behemoth.
Any sniping I do at her in the rest of the piece, if you could call it that, couldn't offset praise as high as this.
The point of the article is not that Sandberg herself screwed up. I'd say she's responsible for almost every dollar of revenue Facebook has earned. The point of the article was that Zuckerberg and Facebook screwed up by hiring her, and the should rectify it by firing her and apologizing with a big severance package.
The point you are making about advertising at Facebook can be made without pointing the finger at one person. It would be a lot clearer, and the gaps in logic more obvious.
Even if one person is at fault (I'm not arguing that), in business, as in all things, it's generally better to focus on fixing the problem rather than giving up on the person. If we fired people every time they made a mistake then we'd all be unrmployed.
I would agree that it is a poor article with little reasoning behind it, but I have no idea what sex the author is nor do I think it is sexist.
If anything it seemed like the author was discrediting her because her strategy included locking out developer. I'll meet you half way on the Miami sentence on agreeing that it was tacky. However, I think you are taking it out of context. It is apparent that the author doesn't like her, but no where does the article mention that she is not qualified because she is woman or anything remotely to that effect.
Please enlighten me. Did I miss a whole paragraph somewhere?
