Whats wrong with using the highly reliable IDFA for install attribution? 1) Allows the advertiser to know exactly which publisher provided the install, thus allowing for fair billing. 2) Allows advertisers to study users on a app-level to see which sources provide the high quality users. 3) Ultimately helps ad networks target more relevant ads to users, providing a better user experience and higher eCPMs for publishers.

You won't see any ad units that you don't like disappear - the transaction point for the advertiser will just be the click rather than the install.

This is only going to push the industry away from the heavily favored CPI pricing to CPC pricing.

Allowing the use of the IDFA by publishers and not by advertisers renders it useless, since it can no longer be used for attribution. I don't think conversion tracking - measuring the performance of ads you bought to promote your app - counts as spying.

Exactly. And the title is incredibly misleading.
