F*ck MZ. He is the last person I want advice from on making the Internet better. FB is part of the problem and I have little to no hope they will ever be part of the solution.
He's rational in a sense, but he very well might not have ever stepped back far enough to really consider broader perspectives with an open mind, even as he reads and hears concerns. He probably reads them all with some strategic/tactical mindset that blocks him from truly getting the point.
