Extract with 4K Video Downloader or youtube-dl, now focus on spreading the truth.

Have you guys looked into building on top of NewPipe and similar? That's what I'd do. Fork, make sexy, add Nostr social interactions, integrate moderated communities.

yt-dlp in the command line for example but it needs to be integrated in other tools and made easier for anyone to upload to Blossom servers (and bypass youtube's annoying checks)

Good point. I guess YouTubers should be able to mirror their own videos to Blossom with one click. And auto-upload to Nostr when they post new videos on YouTube. Of course it would be great, if we have much more videos on nostr, but I guess it would be to expensive to mirror just more or less all videos. Would be interested in your opinion on how well Nostr/Blossom scales regarding data growth.
