For now I don’t think it makes sense to federate large media like videos. The storage costs are just too high to replicate this data all over the place.
The better model I think is to link to content providers with more traditional approach to providing videos. Lemmy is a link aggregator after all, not a media platform.
TBH, I think this was the downfall of Reddit. Reddit had kind of devolved into a cesspit of reactionary videos. Can’t say I miss those, sure it was entertaining, but it forms habits of doom scrolling and at the end of the day, I don’t want it if it takes shitty business models to support such a service.
Lemmy should stay focused on what made Reddit famous: being the front page of the internet, and honest, raw commenting system to hear from the people.
