Maybe they were getting this from some ad networks like Taboola or Outbrain - but then those networks don't usually have enough info to really identify you.
Sure, if they were giving your IP to a telCo who can map your IP to a name if you're a customer - that's identifying you.
It's HIGHLY unlikely this happened at the usual suspects (FAANG).
