The issue really isn't opt-in itself but how the option is presented.

I agree that a lot of people don't read, or attempt to understand the UI being presented to them in any meaningful manner. It really is frustrating seeing that happen.

But, think about the "colorful" option you briefly mentioned. Dark patterns have promoted this kind of behaviour from popups. The whole interaction pattern has been forever tainted. You need to present it in another way.
