Anyway, the title is wrong. All she says is giving users the option to completely opt-out of targeted advertising on their platform would be a payed product.
There's a reason why Facebook and all the others don't offer paying for their services. They want to be able to tell advertisers that they can reach X amount of people. If X gets too small advertisers lose interest and they have to charge paying customers more and so on. I guess at some point somebody did a napkin calculation and decided it's not worth it.
