No? It's not their hardware and even if it was they can't force you to use that hardware. I'm not sure about the laws around it but I do know schools can't force you to agree to contracts (such as EULAs)
Mine too, but it wasn't forced on me. All of my classmates use whatsapp but not having too deal with all the needless stuff on there is great in my opinion
If you use discord on a seperate user profile, you're still using discord, they still get your data. Sandboxing isn't a perfect solution
The correct thing is to refuse, it is your (or your parents) legally owned hardwarw and they can not control it. They can't force you to sign privacy policies
The fact that people are saying to comply with what your school says saddens me
Refuse. They can't force you to use it. If they want you to use discord, say you only use matrix. If they want you to use chromeos, say you only use GNU/Linux
I don't trust lemmy.world because of their banning of piracy
