maybe you didn't read the article it says that Google also benefits from iOS users(although it says it's a risk that they lose the higher end niche), and the "poor" people are the ones actually ditching the google ecosystem entirely. The article never talks about poor people, instead it refers to places where google services are unavailable/unpopular, e.g. China.

edit: For those down voting, could you please quote the part of the article that implies this: " A lot of poor people use android , poor people don't spend a lot and don't click many ads.Therefore Android is doomed."

it actually contradicts the parent comment: " For years, Android apps were a backwater, but sales have lately picked up."

"In 2014, Google Play sold about $10 billion in apps, of which Google kept about $3 billion (the rest was paid out to developers). "

"Google’s app revenue is becoming an increasingly meaningful piece of its overall business, and it is also growing rapidly."
