EDIT to your edit: Key word here is "originally". As in, originally when this started (months ago) there was no plan to make it public. I published it because I thought it was a funny read, you think it's mean and douchey, I get it. You don't have to get all Joe Wilson on me.
The Root doesn't have a public facing site, so I published a digest version to my blog instead. I sought permission from the community to publish it, because I found it to be an entertaining thread, and thought some outside the forum might enjoy it as well. Maybe I was wrong.
I think for many members, this was a channeling of the behavior of their worst clients towards a company that is insulting to their industry. Childish perhaps, but probably somewhat cathartic as well.
When I get part 2 wrapped up, I'll address the issues you've raised, as many other members had similar concerns that it had gone too far, and there was a good bit of sympathy for the designers who put up with them. It was ultimately called off.
