I think it has more to do with the federated nature of the platform. If you are ingesting content from Mastodon for example, # is a hashtag in a post, and you can tag someone with their username with the @ symbol.
Edit: you can tag people here with @ too - such as @knova@[email protected]
probably because a hashtag is already a thing that means something else in other apps. making hashtag mean a community here would give it 2 meaning depending on the app and that’s not user friendly cause people will make mistakes if they move between apps.
therefore a new character was chosen for communities to avoid such confusion
A hashtag fits more for communities than an exclamation mark.

So that leaves a new symbol for community linking
A hashtag for community seems much better than an exclamation mark.
You already said that
But you didn’t say why Lemmy does not use hashtags for communities.

I explained that hashtags use the pound symbol already, and usernames use the @ symbol. Communities needed their own symbol.
hashtags are for hashtags
