No, it wasn't. It was at one time partially owned by NBC. Perhaps that's what you remember.
It's beyond a dark pattern - it's plain fucking disgusting behaviour.

I realise it's comically unenforced, but doesn't the GDPR forbid websites from doing that?
Obvious ugly workaround: use a Private Browsing session for that website.
