I think any big tech company falls into this. And unlike google search, there is no alternative for Microsoft windows. You can change your search engine and keep using a new one without any trouble or training. Off course, you can say that the others are not good enough, but companies don't get dismantled because competitors are not good enough. Switching from MS windows is alas, not possible. The main thing is the large number of applications available for it and not for other platforms, and also needs significantly more training than switching away from Google search.
