A typical employee at any large company is incentivized to:
- Maximize their salary
- Maximize their future earnings potential (e.g. CV)
- Have fun
- Have work-life balance
... and so on. That goes all the way up to the CEO. Pretending a corporation thinks and responds to incentives is folly. Running a corporation like Google is like herding cats. If everyone marched in the same direction, Google would cut through SEO optimizers like a chainsaw through butter. There is no wayh to do that with 100+k people.
Google fundamentally has no financial incentive to fix any problem, since organizations aren't intelligent, sentient beings which act on incentives. They have dynamics from the interactions of 100k+ individual agents.
There is no magical fairy which makes large organizations act in their own best interests or even try to survive. The only reason they do survive is that's as true of their competitors as themselves.
