ActivityPub is embraced by:
- Threads
- Flipboard
- WordPress
- micro.blog
- NodeBB
- PeerTube
- Pixelfed
- GoToSocial
- Akkoma
- ...and countless smaller projects
It is by no means just Mastodon.

This isn’t quite true. WordPress.com announced they were planning on ActivityPub support, but that is a separate entity run by a commercial company (Automattic).
Their plan was to support it specifically on Tumblr, as well as helping fund an open source plugin for it; there have been no plans to integrate it into the WordPress software directly.
I believe they’ve also deprioritised it as they did significant layoffs recently.
