Doesnt this just outsource privacy to another website? Also youtube RSS links are all identical except for the last bit, and that is easy to get by for example opening the channel on any piped instance and copying the string at the end.
RSS - Really Simple Syndication
You can share with other RSS system users news and tips.
Please use English.
The only mentioned benefit seems to be privacy.
Apparently it prevents this auto embedding:
YouTube injects their video link directly in its RSS feeds in a way that will cause some RSS Readers to automatically embed the YouTube video
But it is just a media link. It isn't like YouTube is doing something nefarious. This are just doing RSS (somewhat) like intended. If your feed reader renders these links without any confirmation it is an issue that will affect all feeds and you should change the settings on your feed reader.
In general I like openness providing feeds for sites that don't have them but this seems a little pointless. I guess it is basically a proxy service that hides your IP at this point?
I checked this out when I ditched the yt frontend, but it was very limited in how many videos it could show you, and there was still no way to filter out shorts, I think.
A few ugly python scripts now take care of all that for me using newsboat.
