Kind of. It's a desktop web front-end to Youtube. I'm not sure whether it blocks in-stream ads (and I'm not turning off Ublock to find out), but it does basically reimplement the Youtube interface without many of its undesired elements.
If you feel so strongly about the matter, feel free to not use it. Or better yet, contribute to the project to bring it up to feature parity.
As for the link - I guess whatever parses the URLs on Lemmy doesn't recognise .video
as a valid top-level domain. All I wrote was piped.video
, everything else was added by the website.
More like Newpipe but it actually works (GURU MEDIATION) and has nice UI. I just found it yesterday on FDroid, I recommend it.
