Is Google being Monopolistic?

Before the concept was corrupted in the late 19th century, "monopoly" meant the exclusive right to sell a commodity, granted by the government. (See http://www.etymonline.com/index.php?term=monopoly) Monopolies of this kind are wrong; they fly in the face of the American ideal.

But Google achieved most of its success by its own merits, without the intervention of government. I don't think that it's right to tar legitimate earned success under the same conceptual brush used to attack feudalism. Doing so confuses the issue so much that it's not possible to arrive at a sensible answer.

It seems that you can easily change your Google Account's e-mail to a gmail account but you can not change the Google Account's e-mail to another e-mail account or to another gmail if the Google Account's e-mail is a gmail.
