Google Ads Are a Free-Speech Issue

I found this article from browsing some articles on Slashdot. Basically the article stated that an individual from North Carolina had sued both Microsoft and Google becuase the search engine displayed his advertisement concerning fraud in North Carolina. He demanded that under the 14th Ammendment, the search engines remove the advertisement. However, the US Federal Court recently ruled that ads displayed by search engines are protected as free speech. I found this article interesting becuase it is just another example of the constant scrutiny that Google is under.
