How much of Google's revenue do you expect to be generated from Android OS? Further, Facebook apps are on apple and android products, giving them a larger market share than android alone could ever have. The OS alone will not be generating revenue.
Also, I will add, nearly every article you read on Hacker news is a blog post on the submittors own blog. Is their something wrong with doing this?
If you found it so terrible, why did you continue reading for a whole 5 minutes and not stop after 1, clearly it must have had some value.
Google makes the vast majority of its current revenue from search and email, not from Android. $1.3 billion is projected and is about 3% of $32 billion a year revenue, the vast majority of which comes from search.
