I hate to be that guy but publishing source online for free theoretically involves unbounded distribution costs that can't be recovered. That isn't the issue here but it should be considered before changing a license.
Let not forget that google heavily relies on opensource software. The Linux kernel being the obvious one in this discussion, which they make extensive use of.
Google is worth what, a trillion dollars?
It doesn't if you use a better theory
Google literally has infinite money.
Google has servers inside ISP networks that distribute YouTube videos. They pay nothing for the distribution costs, I think they don’t even pay for electricity/cooling. If they wanted to distribute Android source code, they wouldn’t have to pay a dime.
