Here is how the comparison looks to me: Assume you are a HN user and you heard about this interesting lobsters community.
Case 1: Different website, create an account there.
Case 2: ActivityPub vision, search for !lobsters, click join
Case 3: ActivityPub now, go to website, copy URL into your own instance, search returns nothing, try again minutes later, join.
I fully agree that Lemmy is currently not easier (case 3). Users understand multiple accounts (case 1) but managing accounts, they do not. I belief eventually the Fediverse will be easiest (case 2).
