I notice a different, amazing angle that doesn't really stand out in current comments.
This is a BBC article. UK public broadcasting, paid with taxpayer money and aggressively collected - one of the first things I got when moving to a new home in the UK was letters from tv licensing.
Yet it's all "In the United States". "Federal Law and state law". The US National Highway Traffic Safety Administration that, this Maryland researcher for Mozilla there. There are two references to the UK and Europe (lumped together) that vaguely say, "It's a little better for certain classes of data" and "you can request your data". Which effectively means, "GDPR exists and the UK has its version".
I get the following banner:
> This website is produced by BBC Global News Ltd, a commercial company that is part of BBC Studios, owned by the BBC (and just the BBC). No money from the licence fee was used to create this website.
Thank you. I was missing that info because I do not get that banner, currently surfing that site from the EU without any login.
Visiting the same URL on the .co.uk version gives me a multi-article scroller with different layout and links (including a "What is BBC Future?"), but no trace of that banner. Guessing that you're in the UK from your comment history, my best guess is that they decide whether to serve that banner via geofencing.
