What is the etiquette for posting YT links in this scenario? If the content is from YT I'd prefer to post the canonical link instead of a mirror that may go down or may get hugged to death. If you'd rather view on a mirror I'd suggest you use e.g. LibRedirect. Does this make sense? Are there better ideas? I'd like to promote non-YT frontends but am not sure what the best option here would be.
I would say just post the YT link and let folks do what they want with it. When someone only posts a piped link I don’t bother clicking because they are very unreliable for me and I pay for YouTube so I like to just use it and not deal with the bs.
I can't imagine there'd be any damage to posting two or more links: the YT one, a piped one, an invidious one, etc... All sides of the conversation that matter are covered.
