Yeah, it's like the ad supported Kindle's ... I've got one, I've paid attention to literally 0 ads though. I hit the power button and swipe away the 'lock/ad screen' ... it's completely unobtrusive because I have literally not paid attention to 1 single ad and what I have to do to unlock is exactly the same as I'd do with the non-ad-supported version.
The problem is at least with the Kindle, I got something out of it (a kindle at a discount) and I do buy some books through them every now and then, so they don't have an incentive to fuck up the experience for me.
Google on the other hand has every incentive to continue to fuck up the experience. First, it'll be still ads, then videos without sound, then videos with sound, then you won't be able to start your video back up again until the pause ad has finished, etc...
