@DodoTheDev when I proposed using Linux, I was bombarded with all kinds of safeguarding concerns. I answered every single one, and then pointed out 365 accounts allow pupil A to go home and create anything dodgy they like on PowerPoint, word, sway etc, and share it with pupil B and despite the fact we, the school, have provided the means of contact, we have no idea what has been shared and cannot access it and are relying on parents to report stuff to us. We know some kids have unmonitored internet access so IMHO we are being neglectful in our safeguarding duty as a school to allow it (we're talking 8 year olds here). The responses suddenly went quiet.
