Blueblur in a nutshell.
I'm assuming the original post was commenting on quotes from Kynan.
Kynan, who I adore, is no longer at 343. He joined Blue Point in Austin, TX. I have no idea if Kynan would have negative comments about those maps, but developers aren't in the habit of saying bad things publicly about content created by another studio. In this case, a lot of those maps were creating by our development partner, Certain Affinity, also based in Austin, TX. Personally, I think several of the maps created by CA are my personal favorites from Halo 4 and would defend their design to anyone. However, I don't think anyone thinks any creative work is perfect.
It's far easier to criticize your own work, which any developer will tell you, we do on a daily basis. Developers are usually their own worst critic by a large margin, but often it's not always productive to air those criticisms in public, as it's far too easy for them to be used out of context by folks posting on forums with an axe to grind. I'm not quite sure what you're trying to insinuate with your drive-by vague post, but, based on your posting history, it's par for the course.
