Google currently has a quarterly revenue of $70-80B.
Imagine an internal team launches a new product to collect $100M in quarterly revenue. An earth-shattering success for any entrepreneur.
For Google...it doesn't even move the needle. Does nothing for stock, it's not strategic, and may become a liability later on.
You would need to launch a multi-billion new sub business for it to be of any interest to Google, which is impossibly hard.
