They started pulling that nonsense on me too. About every tenth video has an overlay and there is no "just leave me alone" option. I end up using an incognito tab instead. For the life of me I can't tell what choice they are trying to force me to make and what is wrong with how things are at the moment.
The overlay has changed a couple of times, when they've combined or relabeled the options. The last time I got it, they had removed the "go away" option, so I gave them one of the answers they accepted - "I don't want to use my g+ profile, because X".
Of course, about 30 seconds afterwards, I noticed that the option that actually was most accurate for my situation was Y, but I hadn't clicked on that, so whatever.
