Some corrections from technical perspective here.

This is NOT ActivityPub.

This is Mastodon being SO LARGE of a platform that other platforms like Pixelfed implement their own Mastodon-compatible API's.

Technical proof just in case:
Mastodon API: docs.joinmastodon.org/methods/
Pixelfed API: github.com/pixelfed/pixelfed/b

Same goes for Pleroma and some other platforms.

And this is NOT related to the federation. Federation and ActivityPub come into action when instances communicate with each other.

> Mastodon earns over 19,000 Euros a month via Patreon donations. This gives me peace of mind

Just in case, this is somewhat equal to a salary of 2-4 developers in EU or US. But if managed carefully it still gives Mastodon a stable footing.

Nice article otherwise 👍

P.S. I'd also add that it's a good idea to support your instance by subscribing to donations if possible since a lot of instances are paid out of owner's pocket.
