Err, what?

.edu is a TLD for US based educational bodies. So the reason you don't see a cookie banner is because the majority (AFAIK) of US states don't mandate a cookie banner, unlike EU and UK based sites (like the Natural History Museum, based in the UK). Does this mean the Natural History Museum is a less authoritative resource than anywhere else? I'd say the opposite, actually.

And for the "change a tire" example using a .edu TLD. That's a fantastic example of how to find search results that are almost completely useless for anyone outside the US. What's a "tire", anyway? Oh, you mean "tyre". What's a "flashlight". OK, you mean a "torch".

In summary: there's a world outside the US. It's lovely out here.
