For those who don't know, Github is currently the number 1 repository hosting service, it allows programmers to host their open source projects in order to share it with the world and collaborate with other members of the Github community. To put it simply, use their github profiles on their CV's as a measurement of performance, to show their contribution to other projects and their own projects.
So, the same company that has issues with the word "meritocracy" (because why putting effort in my skills when I can just claim that I'm a minority and automatically win?) issued a Code of Conduct that can be boiled down to "if you agree with our thought policing, you should put the code of conduct file in every project that you host in our website". They want to tell at a glance whether you're with them or against them in pushing the SJW/LGBTW agenda in the world of technology. You even have to be careful of the words that you use when you criticize someone for their code. Tim Hunt turns to be right at every corner, since now you have to be even more careful of what you say to avoid hurting feels.
Naturally, a post of a programmer disagreeing with the idea became popular https://archive.is/SeFrI and the comments burst in flames, some of those calling out third wave feminism out for its bullshit ideology, how you end up walking on eggshells, paying attention to your language and in case the other person gets offended and happens to be a woman or colored... Oh boy. What if you call Sue's code shit and thinks that you're doing it because you're a white male misogynist shitlord?
Guess what happened to the thread: Hidden and filtered. You cannot even search for the thread anymore. But leave it to the programmers to create another thread asking "why did the previous thread got delisted?" (update: even this discussion thread got delisted, in case you had any doubts) and the top response is:
My guess? The majority of comments expressed opinions that went against one of the mods' dogmas. Hilariously, hiding the thread vindicates the anti-CoC position the mods are presumably trying to suppress.
Not surprising. People are aware of it, and they don't like it. And, in case that you're also a programmer and you're concerned with the thought police that keeps getting stronger, always remember "Law 38: Think as you like, but behave like others".
