That’s not the point? The school provides a service and is (probably) not obliged to do so. If the school sets rules on this services, it’s OPs choice to either use or not use that service. 🤔

I have a fujitsu thin client with a 4 core Celeron CPU and 8gb RAM. Nextcloud and Maria DB run in separate containers in proxmox.

I am the only user. I have only office, face recognition and maps installed. Other than that I use calender, contact and Foto sync.

Well, I get that lightning and usb c provide different features, but the dimension of a USB C socket and plug could remain the same if you were to turn plug into the socket and vice versa, wouldn’t it?
