Does Apress squeeze out books without editing?

I'm no journalist. I'm not even good at writing, but then again I'm not paid money to write. But even though I don't have high demands on my own texts I have high demands on books I buy. I recently bought two books from the publisher Apress. The quality of writing in these books have been less than mediocre. This has started me to wonder if Apress editors even reads the books before printing. Perhaps they are more concerned to squeeze out books than making sure the quality of the texts are good.
