Thanks for being so open and sharing this. I truly hope that this is an oversight on their part and not something intentional, and we're just looking for the right person who can "press the button" and grant you a license.
Looking at https://www.threadgroup.org/thread-group, it seems like they already have some access for free ("Academic" and "Associate"). I'll have to review your blog post to see if you already reviewed those and what the specific issues were.
Edit: I see you did mention their "Implementor" membership level, but I'm not sure which of thier points you need to "implement their IP" that the no-cost memberships lack... "Access to IP rights", maybe?
