Is there any recording of his talk or something? Regardless of his actual points, this sounds like an extremely weird thing to do.
The guy is pretty passive aggressive in that thread which makes it hard to take his points seriously.
However, I have the utmost respect to antirez for doing the work that he does, and I think he is an excellent maintainer; his job is not to keep contributors happy but to make redis as good as it can be according to his vision. And while I disagree with some of his decisions, he's doing a great work at that, and I see him becoming more attentive to the community lately.
