"just" seven months ago? In average consumer terms, that was more like a generation or two ago.
I've said this before, but the old saw about all publicity is good publicity is mostly true, it just needs time.. Seven months after a huge data breach, most non-techy people just remember that Talk Talk was on national telly. Brand awareness with no recollection whatsoever that it was bad news, so of course "they must be good 'cos I've heard of them"
