I do find it a bit funny that their adblock-block is to my knowledge just client side JavaScript. Ya' know, the kinda stuff adblock is built to cutout.
Unless they're going to be splicing up videos to put the ads into the same file (which would be astronomically resource intensive) or only allow YouTube in app and in seriously locked down Web-Environtment-Integrity browsers it'll be impossible prevent a device from running or not running code as the user see's fit.
