When has Apple ever said that they would not follow the same rules? They have clearly stated that they will follow the same rules, which is no surprise. It would have been a surprise if Apple had said anything else.
BTW the issue is not simply your buying habits. It's a nuisance to be followed around with companies trying to sell you things related to your browsing or searching habits, of course, but really this is not the issue. The bigger issue is that by the use of big data, For example, Cambridge Analytica bought FaceBook data that allowed them to bias the Brexit vote in a way that has caused untold damage to the UK's current businesses and future prospects, and against what had been the majority preference for the UK to remain part of Europe. The power to influence such things, and to know how to present misleading and skewed information to key groups in the community, effectively undermines the working of democracy and opens us up to manipulation that is more powerful than simply cheating during poling. It risks us being manipulated into conflicts against our interests. It risks us failing to deal with theft and corruption by powerful interests. It can create en environment in which people think that it is reasonable to take part in Extinction Rebellion riots, or encourage targeted flash violence that can damage the malls owned by the competition. This is a much bigger issue than trying to sell you a better mattress or a different brand of washing powder.
