Scripting News cites : “Google’s browser toolbar is raising eyebrows over a feature that inserts new hyperlinks in Web pages, giving the Internet search provider a powerful tool to funnel traffic to destinations of its choice.”
Scripting News goes on to quote quoting Anil Dash: “Google is pushing its ads into content it does not own.”
Like Microsoft’s Smart Tags, that is modifying content that they do not own. If the content happens to be your material, how do you feel about Google infringing on your right to present it as you have chosen? Is this copyright infringement?
