Google employees in an individual-contributor role have limited power to change this if they want to remain Google employees. They're subject to performance reviews on this system, and the expected value of any individual advocating for a change is so tiny, compared to the expected value of playing along with the system and getting their salary and bonus check. If you want this culture to change, you need the people signing the checks to feel compelled to change it.

The practical effect is likely to be people leaving Google because they can get rewarded for maintaining existing products elsewhere.
