Not really. You'd have to be an idiot to attach your name to this given the shitstorm twitter would unleash upon you for questioning the narrative. No idea if it's true but in this environment anonymity is probably the default.
Not to mention the fact that, assuming the writer is indeed a Github employee, the fact that it would instantly place her at grave risk of losing her job.
If this person has proof (documentary, whatever) that their narrative is correct, they should step out from behind the easy cloak of anonymity and show it. Until then, they're really nothing more than a troll.
