It's 2022, I have advertisements served to me though every platform on my phone (email, app store, phone calls, texts, social, web, etc), and I can't even change the appearance of my icons. Windows 3.1 had this feature in 1992. The most asked for feature for years of all iPhone users is visual customization. Sure, you can change font and icon graphics or layout on Android.
What is the possible justification for the prioritization of work at Apple other than to sell you and your device as an advertising platform? Please give the end consumer something they want and like, not the corporate ad ecosystem.
