There is a big difference between agency recruiters and recruiters within a company. I have not had any bad experiences with recruiters who work for a company (that is not an agency). In fact, even agency recruiters, there are definitely some bad apples but a lot of them generally are fairly good to deal with.

If you actually read the article, that distinction is completely irrelevant, since the proper title is more like "Recruiters are a waste of time for start-ups."
