Hard to use that to say he's not a great person to work with. The LA accelerator might have been egregious, and he may be doing a service to other entrepreneurs by publicizing it (there are a lot of incubators today, and entrepreneurs should beware). I do hope in the LA incubator's case that he gave actionable feedback privately long ago.
I totally agree on the cognitive dissonance with bashing YC and saying to never to do it, after getting rejected recently. But I can realize how it might not be a fully rational perspective (he'd probably argue that he's more educated now, and that's why he's changed his mind since applying - my gut is there's some emotions involved, since I can't see a ton of benefit to him to write this so publicly).
