> The ads business or Facebook is based on the very specific data Facebook can provide their advertisers

Again, no it isn’t. Facebook at no point provides data to its advertisers.

Yes, advertisers can say “show this ad to people who are right-wing and live in DC” (although I doubt “dyed hair” is a category). However, the advertisers are never provided with any data about who is in that category. That data never leaves Facebook.
