They've been doing it for businesses for decades so this isn't really surprising honestly

Hard disagree. In winter we have cozy warm clothing, crisp dry air to breathe, beautiful blankets of snow, houses lit up with decorative lights at night, and most importantly significantly less bugs! I love hiking and backpacking in winter. I would much rather sleep outside when it's 0 C/32 F than when it's 24 C/75 F+ at night. Once it starts getting warm here the humidity creeps up and you're just sticky for months. Sitting outside on my porch on winter mornings bundled up in my coat and scarf having my morning coffee is one of my favorite things. If I do this in summer I'm eaten by mosquitoes within minutes.
I'm sure whether people like summer or winter more is heavily influenced by where they live, but here summer is hot, humid, full of mosquitoes and ticks, and just generally all around miserable. Late June through early September is the worst part of the year and it's not even close for me.
You don't necessarily need to take it away, there are other avenues of punishment. Detention, Saturday school, no extra-curricular participation, suspension, etc. I was in high school right as dumb cell phones started to become a thing and those were our punishments if we were caught with phones out. We were allowed to have them, but they had to be either off or on silent, and in our bags (same as CD/MP3 players.) We were allowed to have them out to check them only during lunch and before and after school, or if we had to make a call, in the main office. I completely agree that kids shouldn't be using phones AT ALL during class time, but there's ways to allow them to exist and punish inappropriate usage that doesn't require teachers taking them. Teachers shouldn't be taking phones, that's a liability risk and not worth the effort.
