> 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.
