"looks like some kind of ab testing bug or round-robin servers." Definitively AB testing. The website runs hundreds of experiments simultaneously, on a few pages. Although in theory all the experiments are independent in practice it is often not the case and some bugs show only in some combination of 2 or more experiments. Especially, in such crowded web pages, even technically distinct experiments influence each others UX wise, which can cause bugs of their own (like, two distinct experiments displaying two seemingly contradictory messages). Eventually, the mix of experiments a given user is subjected to can look a lot like an outright lie or bug or scam or deceptive practice (especially when it's a combination of small dark patterns of course), and I think that's what's happening here.
