I'm sure internal politics plays a large role. Managers knee-capping each other and so forth.

But there is another way to look at it. A company of Google's size will not be satisfied by a "small" $10M ARR business or perhaps even a $100M ARR business. It's not going to move the needle. The needle being, effectively, Google's stock price.

There are two ways to move the stock price: increased profit or decreased spend. Increase the pie or stop the number of people eating the existing pie.

All of those projects had more value in being ritualistic offerings to the stock gods. Much like the unreleased Batgirl film had more value being a tax write-off than selling for market value: https://en.wikipedia.org/wiki/Batgirl_(film)
