Why is the Department of Justice suing Google?

Well, they are suing Google because Google is a giant, massive company that has a dominant position in search. In fact, on your phone, you almost can't use any other search engine or at least your phone is preloaded with Google as a search engine and you probably don't know how to change it. The Department of Justice alleges that Google has used its power and its muscle to maintain its position, and that violates the antitrust laws.
