As for the Union Jack: the UK has at least 3 rather different languages (English, Gaelic, Welsh), possibly a few more depending on how you count the different kinds of Gaelic.
Using a country flag to represent a language has always struck me as being silly. Only rarely do they map 1-to-1.

Also, for what it's worth:
> Some people have characterised Tangier’s way of speaking as ‘Elizabethan’ or ‘Restoration’ English, but that’s nonsense. Languages aren’t static and the Tangier dialect has changed a lot because of its isolation. It’s a distinct creation of its own," Shores said.

Mixed with, yes, the variant spellings and word choices (e.g. chips/crisps/biscuits) that make it apparent to British English readers when something is American.
EDIT: Of course, it doesn’t matter one bit in the grand scheme of things—feel free to ignore my pedantry over a silly joke :-)
To use your example, there are plenty of Irish people who speak English but would resent being forced to identify with the Union Flag.
For another example that is very relevant today, there are plenty of Russian-speaking Ukrainians who hate Russia. Using the Russian flag to represent them would at best be distasteful.

For example, the very first English video I got was a South African English accent.
Of the five languages I have configured in KDE, three of them are country-specific. So I use the flag indicator, which is far quicker for me to locate and identify out of the corner of my eye than would be a text label (which would require using the retina and thus more time and attention).
As for English, the United States has far and away the largest number of native English speakers.
Not that I think the stars and stripes has any more right to represent “English” as a concept any more than the Union Jack. If you’re going on origin, why not the flag of England instead?

I actually really like that idea. The US and UK flags seem to represent more culture than language.The moral is: don't try to draw boxes around languages.
All that said, I do understand why someone would want to use flags as shorthand for language. It's wrong, but it's useful.
You would be far more likely to understand any given English speaking person in the USA than in England. It should really be called American at this point.
