I really don't see what's absurd about that. This website is so English language biased it's hilarious.
Btw we're talking about banks not Starbucks or mom and pop shops
As is most international websites. And systems. And content, in general.
It's a sad fact of life that, as we sail into a globally-connected future, the world is going to consolidate on a small number of languages, and the majority of languages are going to be left behind, discarded, and eventually die out.
People want content. They will learn whatever language gets them the most content. Right now almost all content is produced in a small handful of languages, with (in the west) English being dominant.
At this point it looks like English[1] is going to be in that small set of surviving languages.
It's inevitable. Railing against it is a pointless waste of energy.
[1] My home country has 11 languages, all official. Until widespread internet arrived it was common to find locals who could not speak English. Now, I'd be hard-pressed to find non-english speakers, even in the very outlying areas.
That's even more absurd. So now, just because I don't speak Thai, I should reject all Thai customers, since I can't read their names?
