Could you elaborate how that site proves anything? I can create a github page and type "Elon Musk hates all children". Does that also mean it's a proof?
The original source of that info was [1] - a reasonably reputable journal, I believe, and I would suggest an order of magnitude more reliable than "a github page". Not least because you can be sure that their legal team went through it with a fine toothcomb before it was published.
