Can someone tell me why these tech companies even publish these numbers?

It seems like they always end up with egg on their face. And they have no obligation to be transparent as private (or public) entities.

But now they all have to have chief diversity officers and diversity councils and PR/recruiting teams for diversity - all of which cost money and hasn't seemed to move the needle very much.

And which as another poster pointed out, doesn't fundamentally change the underlying issue about who applies to these jobs, who goes to school for computer science, etc.
