No one will trust them again if they make one major mistake, and Ads are a minefield for upcoming regulations.
They have so much money and financing available, instead of being greedy, they should focus on hardware.
As much as I want this to happen. It wont. Just look at the spin given out by either Apple's PR or Apple Apologist:
"Apple were never against Ads. Steve Jobs made iAds." Meanwhile completely forgetting Tim Cook, 2014-2015. "Apple is not in the Ads Business." - In the Context of why you should choose Apple.
"Apple Ads are privacy focused and they do not track you." Cough. They are only personalised.
"Apple is moving away from China." ( No they are not ). "And has been planning to do so for a while." ( No they didn't )
And literally all the Fans reading Appleinsider, Macrumors, 9to5Mac believes in it. As well as all the YouTube repeating "THE SAME" information over and over again.
It's a common belief even on this site. I see it parroted all the time.
