Apple holding the ID information and all that that pertains is the only company I would like to hold that data. I can see no reason why Facebook or Google or any company that profits on the sale of information should have my data. I appreciate that advertisers want to maximize their ad spends but ad-tech has gotten so creepy ... Apple’s move here I fully support. I look forward to seeing apps using it more often and perhaps eventually all the apps I use as well so that I can move all my logins via it.
Apple sells me thousand dollar phones and services. Until they start selling my data to ad brokers and becoming a Google I’ll support Apple on this going forward.
