I got the invite today. My dealership texted and apologized as they were not aware the Limited was a 2.0 and like the First Edition based on the Badlands.
This thread has been dormant for a few months but I just received an email this week for a free one year membership to Bronco Nation. I came in here to see if it was legit and then also had the same question about being worth it once the free part expires. I have a MY23 Outerbanks by the way and still got the invite.
