A highly beneficial side effect is that it disables the main YouTube shorts stream. You still get some shorts for your subs and such, but the bottomless heroin feed if Shorts is gone, and good riddance.
You can remove shorts under YouTube’s time management settings > daily limits > shorts feed limit, you can set the max allowed time to 0 min and the effect is they all disappear.
Oh interesting, I just have a userscript that completely excises shorts from youtube, seems like a neat side effect though. Always a jumpscare to use youtube on someone elses computer and see all the shorts, ads, and sponsored segments. We had TiVo like 30 years ago, this is a solved problem.
