So we have "opt in" so you have to explicitly say yes
Then we have "opt out", where you can take steps to say no
Then you have "nag in", the new popular solution where where you're given a choice you probably don't have any good reason to go a long with, but you will be nagged on regular intervals until you either give in, or click accept by accident. And every time you say no, you need to scroll through a vast set of identical-sounding variations of the same question.
