Google is a monopoly. But this is simply because their product was/is so much better than the rest. Anyone can access bing whenever they want but not many people care.
There's no part of this that is good. Other than as a huge monopoly, they can afford to be huge on R&D, just like Bell. They still fail to make money on anything but ads, though, so it's not turning out as well as Bell.
Sure, other search engines can theoretically compete, but it is an enormous mountain to get enough data to be competitive... and just being "as good" is not enough to get people to switch. So without regulation, google is going to exploit a captive market.
It'd be perfectly fine for Google to allow choosing your own maps provider, or just using geo:// URIs so whichever maps app you've got installed handles location links.
Through laws and treaties we've given the EU the duty to enforce this.
I believe even if Apple had chosen Bing instead most people would have changed the search engine back to Google.
Just like with maps. Most people I know use Google maps on their iPhones even though it has been replaced as default map app a long time ago.
If that is true then I guess Google really has too much money.
