Hey YouTube: UK = GB, and both are English

Sometimes I see help messages that just leave me speechless. This message from YouTube about my automatically-set language preferences goes above and beyond anything I’ve seen in a long time because it has two big "WTF moments":

The problems?

• The red circles: The suggestion that English (UK) is different from English (GB). Psst. They’re the same thing. It’s an exceptional reservation in the ISO standard.
• The black circle: The whole message is apparently not in English because the link at the bottom right corner gives me the option to view it in English. When I click it, I get the same message, but instead of suggesting English (UK), it suggests just plain old English. And oh, it gives me the option to change my language to the real English of English (US).

Hey, I have news for you YouTube: English, English (UK), English (GB) and English (US) are all freakin’ English.
