I'm guessing there's a glut of such comments because most people comment with their first gut instinct to a topic, and a lot of Ansible users' first gut instinct when they hear "Puppet" is "Ooof, glad I switched to Ansible." This particular link is sort of hard to comment on, because it doesn't really say anything about what's different in Puppet 4.0. So there's not really a way to comment on the substance.
