It doesn't really matter that he/they changed MO, because they've already shown to be untrustworthy. You can only get the benefit of the doubt once.

I'm not saying people or institutions cant change. But the burden of proof is on them now to show that they did. A good first step would be to acknowledge that there IS a good reason for doubt, and certainly not whine about 'preconceived bias'.
