Is Google Evil?

This week in Digital Cultures, we looked closely at Google, and how its effected what people know about us. Our teacher said that she wanted to scare us to the point where we think about what we search on the internet, but I was not scared. The question of this blog post is in the title; is Google evil?
In the articles from the book, Googlization of Everything, the author talked about how Google stores everything we search and every website we visit. Google uses this information to help to predict what we are going to search the next time we use Google Search, but it also uses this information to provide adds for us. Google does not sell this information to other companies, but agrees to put up another companies add if we search something that relates to that add in some way. The author also spoke about the privacy settings Google has a default, which is no privacy at all. He also warns us that if google defaulted and was bought out, they would warn us, but probably not give us a chance to delete all the data Google has collected on us.
I don't fully understand why we should be so scared that information about what we like is held by a corporation like Google. So what if they know I search about nerdy stuff or shoes or what clothes I wear? That kind of stuff only means that I won't be so pissed off the advertising I see around the internet instead of seeing advertising that doesn't mean anything to me. And yes, for some people, who maybe look up porn a lot or something like that might not want that shown, but thats who they are. These corporations are not likely to hold this information over us, like we have heard of the porn industry doing. This is because this information is really just for advertising, and that is how these corporations make money. So whats the worse that could happen? Good advertising.. thats very scary...
My point is that we should not be too afraid of what information we share with google. The information we give to Google is not overly secret anyway, and I am sure if any close friends already know the kind of stuff you would search on Google.
