I agree with you to a degree. I considered that as a reason as well, and "meeting people where they are" in communication design is something I think about a lot.

But if using an approachable format to deliver an alternative message was the strategy, I think we'd see a few places where the author tried to stretch the format slightly, to give a few core ideas more chance to resonate. In which case it could have been a masterful use of an antithetical format, to prove and point and enrich the message.

Instead, since the entire post conforms, it feels much more like an internalized autopilot, or purposefully manipulative technique.
