Damn, the trick I used to get around YouTube's requirement to sign in for age-restricted videos no longer works. And it's a lecture about art at a public museum, why is it even restricted?
I guess it's a good way for them to try to get your ID information. I'm not doing it of course... Maybe try to find that lecture elsewhere. Rumble, lbry, bitchute, etc. Looking at the actual situation, I would not be surprise if they extend that to the whole content... That would be extreme.
