It’s like all the developers in the field got handed access to some IP dataset and they’re just looking for reasons to use it. Screw the users I guess?

Even worse when a version is actually different. I had to check the US prices in a store once, it decided "nah mate, your IP's not American, clearly you're a bloody idiot, here's your native version" and even when I manually changed the url to US English, as they did languages based on part of the path, it still decided clearly I must not know what I want. I couldn't even try to infer the price, as the product didn't exist on my version of the site.

And aside from that and language pet peeves, what if you're on Holiday? Or live in an area that speaks a lot of languages close together?

As Cousin Mose said, the language is in the header, the fact that some web devs decide the IP address is clearly a better way to figure out what language you want is insane

I have my Google Account set to English, but YouTube still autotranslates all video titles of newer videos to German for some reason...

That's just how locales work. When you set the language, you also get the associated date/time representation, unit system, etc

My pixel set to Australian English works fine in metric. I presume you chose British English where they use miles rather than kilometres, of course that works for me as I also want Australian spellings

We do both.

A) use the language set by the user in their os/browser B) switcher shows the language name in that language

Done, easy, etc. IMO the hard part are great translations and designs that work in languages where every word is a novel. And yet, here we are.

If you set your language on a website what’s the difference between them using the header versus using the selected language for fingerprinting?

I understand what you’re saying but even I, a person who splits all their traffic between three different VPN tunnels and goes way too far with DNS blocking don’t really care about fingerprinting based on language.

If the person really cares so much they can set the browser language back to English then manually change it on each website they visit. We shouldn’t punish everyone on such a silly privacy preference.

Edit: Yeah of course just downvote me, don’t bother to engage in any kind of dialog.

Have you used the web and/or VPN lately? I send the language header but am bombarded by content in the wrong language all the time.
