literally harmless accessibility solution “abuse” because they don’t like it for whatever reason.
Well, I am calling it "abusing the post body" because it doesn't federate to all services. Captions (or as Lemmy calls them, alt text) does federate better as it was designed to use a more standard federation data type that Mastodon understands.
So, using the post body for captions actually kinda is harmful in the lens of Mastodon users, and other federated services that don't support Lemmy's post body.
I am the developer of Voyager, but there are many great Lemmy clients out there! ;)
