Because EzineArticles.com as a very high rank already with google and it's easy to get ranked, and if you then point a bunch of links back to ezine articles from relevant sources, then google ranks it even higher. For example, Forex Robot is a keyword that can cost up to $20 on Google...there are page one articles on it using this tactic. If you took ezine articles out of the loop, I can almost promise you wouldn't get on the first page.
