Let’s say:
- I am on instance A.
- I browse on a community that is on instance B
- a user from instance C post something on that community B.
Now i want to share a link to this post. Which instance should i pick?
- A my home instance
- B the community
- C the post author
More confirmation that C is the canonical URL. Check the <head> section in the HTML (bottom of the screenshot)
Remember that posts belong to users, the community only does a retweet/boost of the post.

This is why it’s the link provided by the fediverse icon on Lemmy, and the “View original on…” link in PieFed. On Mbin it’s the “Open/Copy original URL”
