Those 70% numbers undersell it. It's basically impossible to use the internet today without touching Google servers. Even if you, personally, completely eschew all Google services, almost everyone you want to communicate with will be on a Google service. Sending an email? Watching a video? Reading a blog? Chances are good that Google's involved.
I agree...I am talking about the data releaed by Google to prove its not a Monopoly. The only reason Google is not considered a Monopoly in laws eyes is that people have the option but they are not shifting. Like chrome supports changing of Search engines. The only argument can be raised against is Google is on Chrome, that everyone is using Chrome and Google products are not working properly on non-Chrome based browsers
