first id like to say that this is my option and that im not always 100% correct. I looked around a bit and managed to find the original 10 page memo https://www.documentcloud.org/documents/3914586-Googles-Ideological-Echo-Chamber.html (here for the pdf https://assets.documentcloud.org/documents/3914586/Googles-Ideological-Echo-Chamber.pdf) and frankly i dont see anything wrong with it, while i do disagree with most of it i dont think that he should have been fired over it. and i definitely would not call it an "Anti-Diversity Manifesto". in fact in multiple places he goes out of his way to state I strongly believe in gender and racial diversity, and I think we should strive for more page 6 either way, id say read over it and draw you own conclusions :D
