‘… does this really matter?’
I think are getting the “this” wrong. Nobody is criticizing him for not having degrees from MIT (or anywhere else). They are talking about his lying about it, and how the open source community values openness and honesty. After he was called out for the lying, he even doubled down and lied some more about how it happened. “This” is the issue. His lack of college credentials was never brought up by anyone.
