Let's say we have lemmy instances A, B, C.

alice from A makes a post "Hello, world" to B. What happens? How is it processed on servers A, B, C and how do users from A, B, C receive her post?

I don't understand the comment. It's like calling the fact that firstName is in the JSON {"firstName": "Bob"} "over engineered bullshit" when they should've made some application specific protocol instead of using JSON. ActivityStreams and ActivityPub are built on top of JSON-LD to utilize existing libraries to represent linked data (that's what the LD is). To specify what schemas are used there is a "context" field. There are other schemas as well. Take a look at https://schema.org/ to see them.

If it feels over engineered it's because it's meant to be able to represent a wide variety of types of social media and typical interactions with them. I seriously doubt Mastodon (micro blogging) and Lemmy (link aggregation forum) would be able to interact easily if they weren't "over engineered".
