It's not embarrassing in the sense of showing things that are objectively and rationally bad, but it's embarrassing in the sense of showing things that Google would rather not have public (internal social-media posts by individual employees, with names attached, that almost certainly reflect personal views and not the company's marching orders, and are written with the level of casualness you'd expect from social-media posts in a non-public forum). It seems to me that a good part of the the purpose of including that many screenshots in the lawsuit is to make the relevant individual employees uncomfortable.
read the class action filing. It's incredibly damning to Google.
(Full disclosure, I'm a Xoogler, who left a couple of months before Damore. I am good friends with many of the people categorized as hostile in the filing.)
