Literally the second sentence says it's a clothing store

(ignoring the fact that it's extremely well known in the UK and doesn't need introducing in the UK)

It's a BBC article for a British retailer. I reckon the knowledge was reasonably assumed for the intended audience.

It’s extremely well known in the UK which is the intended audience, although even here older readers might not have heard of it

Second paragraph mentions that it's a "clothing and beauty store".

For others its a huge online fashion retailer in the UK (and maybe elsewhere?).

Maybe the hackers were trying to do us a favor?

You can read any of it? I just get told to fuck off without a subscription.
