Having the default box being "on" is only for the purpose of hoping people click through without realizing.
There is literally no other argument here. "Consent" is: "Hey do you want this, yes or no?". Not "We are assuming yes unless you explicitly tell us otherwise".
Disagree, no matter the level of detail, having "yes" automatically selected is an assumption. What purpose would it have other than hoping people will just select the defaults and ignore it?
Scare away from what? Data collection? I mean even in that wording you are saying there is something to be scared of. It should be up the user. If you are saying "non-power users won't fully understand what is being collected and might get scared away if it isn't the default option" then that is even worse TBH. Preying on people not fully understanding what's going on.
