I can still see some local businesses -- albeit with the full page modal popping up as I scroll. Can people post examples of pages which are no longer accessible? Maybe this is being A/B tested, or only applies under certain circumstances?

On mobile, I don't get a full screen modal. Just a small banner at the bottom that can be closed. This doesn't sound like something that would be A/B tested, since that requires some sort of audience to segment by (typically user id).

You don't have to be logged in to be tracked. Facebook Pixel is one way, via a unique 1x1 transparent image on each page.

Yes, but segmentation by that would be prone to high error rates most likely, and result in error rates too high to gather meaningful data from A/B tests like this.

Yeah same, just tried several fortune 500 companies in incognito.
