The fb and ad-tech argument will be that "non-customized" ads are bad because of the low match with user interests. So one ad will cost you a lot more displays for getting a click/worth view. But this is maybe not a bad thing in itself. When you see the benefits that google, Facebook and co can extract from ads, you can see that the 'pay per views'/'pay per click' rate is probably way too expensive compared to the marginal costs of running the business. So, contrary to people saying that this will kill all the business financing with ads, I think that it could be a good reset to still be effective but just with less margin for big ad techs.
