In my experience, they not only deliberately increase volume to pretty much screech whatever insipid bullshit is being offered at you, but they also can sometimes run for dozens of minutes unless you manually go to your device and press "skip". TV ads never did these sorts of utterly shitty, tedious things.
I even wonder how anything so fucking hostile and annoying to a YT free user can possibly be effective? Who's actively paying for all this garbage ad placement with such scummy little playback mechanics?
