When I read these kind of articles I'm always curious to see the professional background of the author. Not to criticize, but to see if he/she's talking about something he/she saw in scale or not.
Because if you're working with a very small code base then I may even understand sentences like "I am against unit tests in general". I've never met people who work (or worked) in very large companies being against, at least, unit test.
Where hundred/thousands of people touch the same code .. not having unit tests, in the long term, is a suicide.
