Whatever the views are about MBFC, Tesseract integrated it better than LW's bot. If you don't like MBFC, it's just an option in your user settings to turn it off for Tesseract, whereas the bot caused a bunch of problems that weren't even related to concerns about accuracy and bias. Drive-by bots can be annoying, because it leads people to believe there's legit content where there isn't, and not every client respected LW's bot use of spoiler Markdown, so they ended up with a massive comment from it that dominated the screen.
If Lemmy / PeerTube inter-op was better, there'd be less need for Lemmy users to be doing what they're currently doing with posting them separately. (It's good that more people will see this video, but it effectively leeches votes and comments away from the original creator).
The first link in the cross-post chain is to https://piefed.social/post/413111, which is for the channel, and shows that it was made 4 weeks ago, and includes a comment from the main LW admin.
Your suspicions about this video seem off, but if you want to keep them, they should be directed at person who posted this old video into Lemmy, not the video's author. As well as a PeerTube instance, Jeena has a PieFed instance, and it seems reasonable enough for him to use his own channel to discuss things that have affected him and are relevant at the time.
What's even weirder is that this video was already posted to !videos@lemmy.world by Jeena a month ago, and OP commented on it then. It doesn't get picked up as a cross-post (by either Lemmy or PieFed) because PeerTube has 2 different formats for its URLs (a recent change to PieFed means they get they will do from now on, but it doesn't apply to old posts).
I'm not personally in favour of ideas about voting privacy (I think it's a bit anti-Fediverse and hampers backfilling), but those who disagree tend to feel more strongly about it than I do, so I try to avoid arguments about it.
I think they still need a separate user account. For one thing, a PeerTube channel is 'attributedTo' the user account, in the same way that Lemmy communities are 'attributedTo' the moderators. A Group belongs to at least one Person, it can't belong to itself. Another is that it allows for creators to comment on videos, and either be recognised as the 'OP', or as a fellow content creator.
In terms of rendering things like Likes and Dislikes, it has the info in the backend, so it may as well. They don't Announce votes like Lemmy does, you have to activitely fetch them, so the channel as it exists on PeerTube provides a definitive source. Likewise, there's all sorts of reasons why comments get out of sync, so the channel provides an authoritative place where you should be able to see them all.
There is a friction though. I like the idea of a place that only open to people willing to create content, and isn't interested in signups from 'lurkers', but providing a mobile app doesn't seem compatible with that.
That doesn't seem unreasonable to me. I'll get in trouble for saying it, but I think that PeerTube is for video channels what Lemmy should be for communities. It should be that if you want to start or moderate a community, then you sign up to Lemmy, but if you just want to interact with one, you use a user account provided by software that's fully geared up around users (e.g. Mastodon).
Ignoring for the moment that Lemmy's federation model hasn't been widely adopted, and that comments from Mastodon that appear in Lemmy often have annoying Hashtag / Mention spam, my fantasy version of a post in a Lemmy community would look something like https://tilvids.com/w/wjTD7fp9qy4KmTkBdSoWyc, which was created by a PeerTube user, but has been commented on and voted for by users from Mastodon, Sharkey, PieFed, other PeerTube instances, and MBIN.
Amongst those subscribers, commenters, and voters should be Lemmy users, of course. In this thread, it feels like PeerTube is being criticised by people who want to use it in a way that it's not designed for, because they can't interact with it from their Lemmy account. If inter-op was better, there'd be no need to create a new account anywhere, and it would have a network effect - the channels that people are trying to discover would already have been brought in by other users, and findable through a conventional Lemmy search. Also, the votes and comments from Lemmy users that are currently going to whoever takes a PeerTube video and posts it in the likes of !videos@lemmy.world, would instead be going to original creator. This would also aid discovery (since people would be more likely to see the channel in 'all'), and might have also some incentivising influence on the creator.
That view of The Linux Experiment is quite similar to the view from lemmy.ml, with the latest post also being from 9 months ago. I wonder if your PeerTube instance and Lemmy 0.19.x have the same problem, where "something changed" at PeerTube, and new videos stopped appearing at federated sites that didn't change to accommodate the update. Are you running an old PeerTube version?
alien.top got people's ire because it created a different bot account for every Reddit user, but this one just looks like it posts everything as 'LemmyLinkBot', with the Reddit user as the first line a post / comment.
If you're not seeing anything at https://lemmy.world/c/resist@fedia.io it'll be due to a setting on your account (view the link when logged out to confirm). There's loads there when I visited it.
It might be serving a dual purpose though - it's a more dynamic experience for the viewer, than just a list of the upcoming shows, but it's also a technique that allows them to repeatedly lean on the mega-hits (Stranger Things & Squid Game), while yadda-yadda'ing the rest of the content (consisting largely of stuff purchased from broadcasters, mid films, and a graveyard of cancelled TV shows).
Yeah, PieFed is more geared up for what ActivityPub terms 'Groups' (communities on Lemmy, magazines on Mbin, video channels on PeerTube, categories on NodeBB, certain type of blogs on WordPress, a.gup.pe groups, etc.).
Whenever we see someone from a platform like Mastodon, it's because they've interacted with one of the above Group-types. There's already a bit of inter-op that you don't find on Lemmy - e.g. you can create a Poll for the people following you as a user, and they can vote on it - but there isn't the ability to follow them in return, like on Mbin. I believe improvements to things like this are on the 2025 Roadmap.
If you don't want to resurrect an existing community, you can create new ones by accessing Lemmy with a browser (not an app), and clicking 'Create Community' at the top of the screen.
More so 'other Fediverse socials'.
Here's an example on PieFed, that's a PixelFed user tagging their photos with 'dailyphoto' and then sharing via a.gup.pe on Mastodon: https://piefed.social/tag/dailyphoto
