Being fair here, this is just another day that ends in Why in regards to the enshittification of the Internet in general.
Youtube for much of its history has always added features that no one asked for and sometimes being as invasive as this along with removing features everyone liked (from forcing people to use Google+ where no one asked for this back then, to removing beloved features like the now defunct Five Star rating system, and Google adding their invasive tracking algorithms being part of the Youtube ecosystem).
Youtube has been ass for many years and at this point it should surprise no one anymore whenever they do shit like this now.
