We don't even know the whole story. The "woman" who sent the note is most likely just be an automated script.
"Hey boss,I tried cloning the Github repo of project X, but it says it can't be found, and I noticed our org page on Github is gone."
"Oh yeah, they sent us a message about the use of the word 'retard' in when referring to phase shifting."
"Oh, so they deleted our organization?"
"No."
"Oh? Well why can't I view it, weren't the projects public? What did you say to them?"
"I didn't say anything, I moved us to a different host."
My point is simply: if Github is flagging content based on perceived personal morals (not ever being allowed to use the word "retard," even in legitimate contexts), some choose not to associate their work with them.
