As it is, og-embeds do work for video and audio from a few different providers.
A size limit affects both equally.

That's only for the web service. Workers and R2 let you do video just fine. And small videos don't need any fancy logic, just toss them over http.
> Size uploads could help in that situation, but it's a bandaid on a bullet wound when the video still gets played a million times, y'know?
No, I legitimately don't know. Why is it different from an image that gets a million views?
It's not a good way to do it, though, and it's worse for Bluesky because it implies that in order to move your PDS (one of the best features of the design), you'd have to pick up the freight for video that already exists. If PDS mobility is important, attaching large economic strings to that is a big disincentive.
I mean that's the whole point of the Fediverse, a federated network of independent nodes. Of course the nodes take care of the functionality.
If you want to be Twitter, you'll end up being Twitter. We already have one of those, it sucks, and we don't need another one.
Social networks go to crap above a certain scale. If everyone can see your posts, you'll write posts to be seen by everyone. Which, as it turns out, ends up benefiting no one. The magic comes when there is a community, where you give a shit about the people you're sending messages to, and they give a shit about you. If the community is too small, then nobody bothers with it and it dies. If the community is too large, then it ends up being old men screaming at clouds, and (see above) we already have one of those. So a platform that is good enough to use, but limits the number of disaffected members, is the only thing worth creating.
If something I'm saying requires a video, then I can always link to one. If something someone else is saying requires a video, and it requires the video to be immediately visible while I'm reading whatever they're saying, then there's a good chance I'm better off not seeing it anyway, even if I think I want to.
(Ironically, in this post I am an old man screaming at clouds...)
