For one, even if I wanted to use it, piped never works for me.
Second, on mobile, my alternative of choice doesn’t recognize everyone’s non-yt links, so it removes my choice in the matter.
Third, I have no reason to trust the weird-ass domains I see, and to un-fuck the url takes much more time then just handing out the original YT links and letting people choose for themselves how they view the video.
Interesting, I’ve seen Piped/Invidious given as the only link… twice I think. Perhaps you’re in privacy-oriented communities more than me.
I do post a tracking-parameter-free YT URL + “(Piped mirror)” when I share :)
