I would say that it depends very much on what you do. If your main income is advertising you will definitely want to watch it closely, have a good reputation and a conversation with your customers. And, as the article states, it can affect your brand severely if you run "punch the monkey" ads. That said, running your own advertising is not easy. You need IT infrastructure, a sales department, customer relations, etc. If advertising is not paramount to your business maybe it is better to focus on the things that are, and outsource advertising. After all a company has limited resources and must spend them where it matters the most. I'm sure there are ad networks that cater to a more upscale audience (eg. no "punch the monkey ads), and if there aren't then there is a great business opportunity in creating one.
