This article raises some interesting points, but ultimately I'm skeptical that it will go as far as described here. Mainly because one of Google's greatest strengths is providing a high quality user experience, and I just can't see them sending a user's contact data directly to several call centers as a result of one click. I think going down this path could be a really bad move for Google, and it's in their best interest to keep at least one party in between themselves and aggressive telemarketers.
