> Google's search monopoly abuse created a monoculture (well OK duoculture if that's a word) in the mobile phone OS market.
It was Microsoft that killed WebOS, Symbian, Asha, Maemo/Meego, Melemi, Kin, WM6.x, Nokia-X and ultimately WP8 and W10M.
Microsoft pushing WP into 'Microsoft only' corporates probably helped kill Blackberry too.
Google is big in search because it gives the best results. I have no idea why you think that people buy Androids because Google has the best search engine. Any phone can use Google search, or any other search - they can do it in their browser.
No. They buy Androids because Microsoft killed off everything else except ones they can't afford.
