The cost of a phone becomes a barrier to scaling fraud because once you use a phone for fraud it can be blacklisted. Advertiser fraud is hardly the only type of fraud. It happens with services you directly pay for like ridesharing and food delivery as well. The cost of fraud becomes another cost for a service provider and prices for all users need to be raised to offset losses from fraud. For smaller businesses without the brain power to combat fraud, their margins will be greatly hurt by fraud, making it harder to compete. I'm in favor of what Apple is doing myself, but it's definitely a legitimate unintended consequence of this measure. What would be useful is if Apple became the gatekeeper for tracking fraud and companies could report ephemeral identifiers for fraud that only Apple can de-anonymize and then Apple provides fraud scores for ephemeral identifiers on account signup.
