Buy a new Apple Watch and notice that the settings app with have a [1] badge trying to upsell you to buy AppleCare+. They obscure dismissing these by clicking the "Add AppleCare Coverage" button and then having a button that says actually no.
Not as egregious as what windows is doing with copilot everywhere or sneakily flipping user-toggled options during updates, but it’s all some degree of gross.
It's certainly not as bad _right now_ as what you'll see on Windows 11, but this is something that will almost certainly only get worse over time.
You don't need to buy a Windows Watch to get ads on Windows though. They'll be right there anyway, and more of them.
