If you haven't figured it out yet, aD is only interested in Real Oragnizations because they're the only ones with the cash to pay their steep hosting and development fees. It follows that their (current) chairman is not that interested in technology their Real Organization customers don't want.
Even though he's not with aD anymore, he still needs Real Organizations to pay his bills so he can pursue his research and teaching.
Furthermore, his comment is not a senseless pgsql bash; it's entirely true. High availability is a difficult and nasty problem, which the pgsql people are beginning now (with the release of write-ahead logging) to attack.
