For me, the Fediverse is about diversity and inclusion, not the homogeneity and exclusion being promoted by the Foundation (should be called the #ActivityPub Foundation). If this were *just* Meta, it would be expected. However, I'm disappointed that the other participants support this misinformation campaign in the name of "education" (and the possibility of Meta sending some pocket change their way).
I see discussions sometimes about developing recipe applications for #ActivityPub/AS2. In that spirit, I wrote a blog post describing how to use the schema.org Recipe type in an AS2 conformant manner. It's mostly a thought exercise about possibilities since most AP implementations won't render an AS2 conformant recipe correctly, if at all.
