What's there to investigate? What's more likely, that people obsessed with social justice latched onto a story about a guy who gave a clinical discussion about rape statistics [1], alleging him to be a rape apologist, or that there's a conspiracy by the US government to smear Linux contributors who don't like backdoors?
They're not mutually exclusive, but someone attempting to connect the two will have to provide some evidence. So far, I've not seen any from anyone.
I mean, how exactly would this theory work? Intel/Microsoft/FBI/NSA is paying or fomenting "SJW trolls" to cause havoc and slander anyone who gets in their way of implementing a potential backdoor? What'll happen when they're up against cryptography contributors who are super progressive or have a "clean record"?
To me this seems way more likely to be just typical social media outcry and hyperbole with nothing nefarious underneath it. And in this instance, it just happens to have affected someone involved with Linux cryptography.
