Peertube has other advantages, among which interoperability. A relevant quote from the main developer:

“Where it gets really, really exciting, is that when you respond to a video status on Mastodon, the message will be sent to the instance of PeerTube. Your response will thus be visible beneath the video, in the comment space. And yes, if another person at the other end of the world responds to your comment via their instance of PeerTube or Mastodon, you’ll see it as a response to your status in Mastodon. If tomorrow Diaspora (the Facebook alternative behind Framasphere) implements ActivityPub, it will work in the same way. We’ll have plenty of platforms that are capable of federating comments.

Free alternatives are criticized, often rightly, for not having added value compared to centralized platforms. With ActivityPub, we now have our first big advantage. Because on the centralized platforms, you’ll have a hard time viewing, under your YouTube video, the reactions of people who commented on Facebook, Twitter, etc. ”

I consider it an advantage to not have those comments. Context matters. Signal to noise ratio on Facebook is close to 0 for most things that are open to everyone. Specialized subreddits have a good SNR. HN can too. Probably closed Facebook groups do as well.

And context matters. The discussion about a Blender tutorial will be different if posted to a group of beginners than if a group of professionals were to comment on it. If I want to help people learn Blender I can seek out beginners and help them in their groups, but when I am not looking to spend time helping beginners I’d rather not have every comment by every person wondering about every little detail show up.

It's not really a problem. Pleroma for example already offers ways you can filter out certain platforms from communicating with you (or do transforms on messages like adding Subject lines or hiding the message body behind a button).

PeerTube could do the same; hide content you don't want to see below your videos or maybe whitelist certain places to allow commenting from them.

That sounds like a job for filters, which could be provided by browser extensions, userscripts, or forks of the platform hosted on other sites.

Question: how does moderation work in ActivityPub?

[otini]

There is no notion of moderation in ActivityPub itself AFAIK, but I suppose you're asking what happens to e.g. comments that have been sent to federated servers/software and then deleted on the original platform.

In general, when that happens the comment is removed on the host platform, then a deletion request is sent to the federated platforms. There is no guarantee that other platforms will delete the content (although if they don't, they are generally considered malicious and should be reported), much like deleted forum posts can be viewed through WebArchive.

Given the general quality of YouTube comments, this is a bug, not a feature.
