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.
