I can empathize with the author and am familiar with the history of his project. In my case, I created a Python framework for the Alexa Skills Kit https://github.com/johnwheeler/flask-ask and worked on a blog post with Amazon. My hope was they'd appreciate my energy and passion for the Echo and work with me, but I feel like I've been largely ignored by them aside from being labeled an "Alexa Champion" which is meaningless to me.

As my framework is becoming more popular, I wouldn't be surprised at all if they released a competing framework locked-in to their infrastructure (after seeing how they did Chalice), and it's their prerogative to do that. But as a developer who made a high quality product people want, of course I'd rather they recognized the value I've created and worked with me instead of against.

They have zero obligation to, but if you're going to build on open standards and encourage community involvement, provide incentives for the community's hardwork aside from labels. Definitely don't disincentivize by doing wait-and-copy.
