> when that's what most users want anyway

Not sure about that. A lot of people really couldn't care less if their search results came from Google, Bing, Duck Duck Go.

If you ask them, most of them would probably say Google since that's the only search engine they know.

But if you just replaced Google with Duck Duck Go, I'm sure most people wouldn't bother to switch it back.

Defaults are very powerful, otherwise Google wouldn't pay billions to keep them the default.
