Great catch! Many years ago this worked exceptionally well with Google translate.

Can't say this works for me, for this article at least.

Cool! Any other sites this works for?

Anyone know why?

I'm guessing it must be because of some kind of deal between Microsoft and Financial Times. If that's so then probably there are also similar deals with other publishers.

Edit:

ChatGPT seems to disagree with me:

(It says that it's more likely just an unintended side-effect of the mechanism that FT.com uses to let search engines like Bing or Google index their full articles.)

This is what I've heard in the past: the companies want their articles to be recommended by search engines, but want the consumer to pay for it.
