I think the post is negative. With all the awesome stuff going on in tech, I don't think we need to spend our time writing (or reading!) negative posts like this. It's unlikely to help anyone and only serves to get the rest of us all upset. Google has done some awesome stuff and the experience of a few (or even a moderate amout) people who have worked there isn't helpful to the conversation.
Good news is fluffy candy that is tasty but not very useful. Bad news is harder to eat but is much more useful for survival reasons. Bad-experience outliers at Google are then more interesting than average or good outliers. Having a pointless conversation about the joys and successes of Google really doesn't allow me to "know" anything, which is the point of coming here.
