Agreed with @robin.berjon.com on avoiding anything that sounds like protocol supremacy.  In fact it might even be worth pointing to Germ as an example of going faster and further together (and cooperating) across protocols.  

In the last section, not sure about the "AT Protocol *needs* you to join us".  Maybe something more like "Please join us!"  

Otherwise, a very good articulation of the strengths of the protocol and the collaborative style of the developer ecosystem!

Here's a few examples to start things out (bearing in mind that I am not an accessibility expert!):

- Suggestions on how to write good alt-text from the American Federation for the Blind, WebAIM, Harvard's Digital Accessibility page. These are hopefully useful for everybody!

- Emoji and Low Vision, from Perkins school for the Blind (the best practices are near the end), again hopefully useful for everybody

- Accessibility resources for Mastodon and compatible software is something I put together to help people who use assistive technology. Are there similar pages for Bluesky or other ATmosphere software?

- For developers and testers, the W3C Web Accessibility Initiative and WebAIM have a lot of resources. WAVE Web Accessibility Evaluation Tools and WebAIM's contrast checker are usefull free tools to help check different aspects of accessibility. Keep in mind that these don't substitute for manual testing, or usability testing with people with disabilities! Still, they're very helpful at finding some glaring (and typically easy to fix) problems.

Other suggestions welcome!
