Facebook Monopolization?

Facebook is used by companies to connect with their consumers all around the world. Everywhere we look, whether it is online or the billboard we pass everyday on our way to school, we see "Connect with us on Facebook!". Even Bucks County Community College is sending out ads about Book-buy Backs and are stating "Your Friends Like This!" in reference to the Facebook Thumb. This is becoming a controlling factor in the world, and in the future, Facebook will be solely involoved in every corporation in the World, which can result in a monopolization of marketing in every aspect.
