Is Google now a monopoly?

The competition is alway a click away.

Everything Google does, there is an equivalent service somewhere on the web. It doesn't mean that the service is better, but it exists nonetheless.

Beside, I would be suspicious of anti-trust laws and the regulators as well.

Can you be a monopoly when most of your stuff that could consider you a monopoly is free and/or open source?
