They're not going after the code, they're going after the programmers. If the coders say anything un-PC, then they can be disciplined. Since there is no mention of the code they contribute, I am guessing they assume they can keep the code.
I think they'll be in for a rude awakening.
I've noticed there are a LOT of linux people that are classic liberal types. Which means I think you're right. The fork they're creating I hope will simply leave the SJW's behind.
