There are other such media hypes which you can explain like that without involving a neurologically active parasite. For example the belief that whites are being systematically replaced by blacks/hispanics/muslims/jews/... Or the belief that there is a single supreme being in the sky, watching everything we do, having killed his son for humanities sins. There are no rational reasons to believe any of this, still, many people do, with lots of media helping them reinforce those thoughts in quite effective bubbles.
There is a miniscule minority of folks who care and disable as much of that as they can, but the vast majority doesn't know how and doesn't care. I even know lots of people who work in the industry and just don't bother disabling any of this because they claim it's all unavoidable anyway, and they are probably right. Oh and they had that attitude already 10-15 years ago.
So, this is already a thing if the past. And we are at a point were even if your devices are not tracking you then everything around you is. Each Tesla parked on the roadside films you when you walk by. Each phone close by tracks that your phone is close by. And nobody cares. Heck, people argue it's for the better, imagine somebody getting raped, so good we have lots of cameras close by to find the bad guy! As if society is any safer for it than 30 years ago
So the kids need to figure out that in order to do this kind of thing they need to attach their watch to some less-cool kid's wrist that stays at school while they do the fun things. At least that less-cool kid hopefully gets some kind of reimbursement for offering that service.
