Press coverage of voluntourism

An article on the CNN website discusses the reverse culture shock that people sometimes experience when they return home to the US after volunteering in another country.

While I thought the article made some interesting points, I was disappointed that it gave so much coverage (and, essentially, free advertising) to a for-profit tourism company, i-to-i.  When there are so many excellent non-profit voluntourism operators out there, why give all this publicity to a company that profits off the altruism of its clients?
