What data? Because if I look at the data points for Apple Advertising, than it is nowhere near the amount Meta or Google are collecting.
In addition, Apple is very transparent about what they collect, see https://privacy.apple.com to know what they have on file linked to your Apple ID.
But if you have a source that this is not the whole picture, I’m very interested to learn.
I would totally love that. I always loved to have an iMac G5 one day when they were still on sale. Unfortunately I never was able to as it was out of reach given my budget back then.
