Turns out Google has spent a ton of money on diversity and it is still an organization that is overwhelmingly white and overwhelmingly male.
Here comes James Damore with some real, practical, research based ideas on how to improve diversity and in one memo he exposed how little Google has actually done to improve its diversity. Damore essentially became the kid who yelled out that the Emperor had no clothes.
In Googlestan, that kid loses his head.
The social justice warriors were just useful idiots for Google. They could distract from the fact that Google has poured money into diversity without actually diversifying.
