You should read the article :) It's very well written and I found it quite informative. I knew nothing about Elsevier other than that I have used some of their textbooks when I was in school. They were very expensive.

The only thing in the whole article that I feel qualified to comment on was his assertion that Trader Joe's mistreats their employees. It must be a regional thing, because the TJ's around here are excellent places to work (anecdotally and based on my long chats with employees, as a frequent shopper).
