I’m talking about first and third party websites tracking you. I don’t use Chrome or Opera, but I’d rather only have to trust a browser of my choice, than having to place my trust in thousands of different websites.
The point is, if you care about tracking and privacy, you shouldn’t be using Vivaldi in the first place.
I can easily go without using my phone for extended periods of time, and always have been. I’ve never really been “phone addicted”, and never used my phone during class - despite having one for the entirety of my school years.
That still never stopped me from not paying any attention in class. Drawing on a book/desk, talking to the person next to me, looking out the window, or just spending time with my imagination were things I did too often, and I never needed a phone for any of it.
I seriously doubt banning phones would make much of a difference, other than pissing plenty of kids off. You’re essentially being forced to go to a place, every day, where you will be stripped of your personal belongings and are not allowed to be in contact with the outside world.
