Are you kidding me ? Mobile ad revenue for one ? This comment shows you are not acting in good faith or just plain anti Google.

This is funny. You're making the point Android is successful as a product because it provides google with "ad impressions" which is exactly my point, Google knows only how to make money one way, with ad impressions. Android the company wasn't successful commercially (no revenue from licensing, not self sustainable) and was acquired quite early when they realized it wouldn't be. Android itself is a huge money pit for Google, and it's worth it only because it creates an avenue to monetize mobile. In commercial terms that's a "loss leader", not a profitable product.

Stick to engineering, it's better.

In the same way that BMW builds "only cars" ? The Play Store gets 30% of in app purchases too. First party phones are sold at profits. The collective revenue of Google due to Android is a big net positive. Not to mention the stickiness to Google products that results too. You don't know anything about business and yet you call out "all the Googlers" who don't succeed at startups. Stick to trolling on HN and feeling good about yourself. Google and Googlers will march on.
