FWIW, a GitHub employee just said on stage at the AI Engineer Summit that this claim is "not true" and that it's a roughly $100m ARR product (first keynote speaker in this stream: https://www.youtube.com/watch?v=qw4PrtyvJI0)
Correct, but he also explicitly said the reports that it was losing money were "not true". Given that he's a VP at GitHub, I would consider him to be more authoritative on the matter than the WSJ's "multiple sources."
