Dislike is an understatement, I believe he's being disingenuous in that blog post. I don't want to speculate on his motives, your guess is as good as mine.

Even though GPG has been around for almost 20 years, there are only ~50,000 keys in the “strong set,” and less than 4 million keys have ever been published to the SKS keyserver pool ever. By today’s standards, that’s a shockingly small user base for a month of activity, much less 20 years.

Published keys are not a representative for gpgs userbase, a great amount of 'powerusers' (whatever you want to call those who need encrypted messaging to work) will not publish their keys for numerous reasons, only some of them technical.

Cryptopartys started like this and political activists still do this: you exchange keys in person, you'd never ever publish them on the net, you would not be part of moxie's 'shockingly small user base'.
