Blaming the EU is a common escape strategy, but I don't believe it in the slightest. Mind, I wouldn't believe anything coming out of the modern Google except "we want to make tracking you easier so we can sell more expensive ads".
Edit: if the evil EU "forced" them to require a credit card or my ID to watch Samuel L Jackson saying "motherfucker", why hasn't the same evil EU forced them to make it easy to opt out of all tracking?
I suppose if you have verified your age in the past (for example if you bought something from the play store?) then you can watch the video freely. Try and watch it while logged off.
