There are appropriate and inappropriate avenues for disagreeing with corporate policy; publicly on a large mailing list is going to get you in hot water no matter what the policy is.
I guess I take issue with this. Google encouraged discussion and disagreement on large mailing lists, unlike most companies. It doesn't seem right that Google would simultaneously sollicit such feedback and then punish somebody for giving them negative feedback.
"It doesn't seem right" is one thing, but that's not why it's still brought up 3 years after the memo was written. A lot has gone on in the world in the past 3 years that doesn't seem right that we've forgotten about or didn't hear about in the first place. Damore is used as a data point (in fact, as a central data point) in the thesis that "political correctness gone awry" or "social justice warriors run amok" are problems that rank highly in a list of society's most concerning. I think it's absurd. That this random dev's firing is doing so much work in bolstering this thesis just highlights the absurdity.
