I'm pretty sure you will need the creator's permission to re host the video. Otherwise it's just piracy. In the LinkedIn case the scraping was allowed, I don't think that HiQ is creating a mirror. Also there's a case for LinkedIn not having much copywritable content there, only information. YouTube's real moat is that after years of operation they're managing to maybe break even, even with Google's insane infra. It's just doesn't seem that profitable to host all the videos for free.
