Fuck it, rant time.

I was IT lead at an education trust (kinda like a school district but bigger) covering K-21 for a long time, managing a few thousand endpoints for a few thousand students. Laptops, desktops, tablets, smartphones, digital signage and embedded; devices belonging to schools, partner organisations, staff BYOD and student remote learning; structured IT suites in school campuses, stateless networks for anything portable, antique appliances that simply must work but also be accessible to particular people from anywhere; it goes on and it never ends.

No-one has time for that.

From a few central interfaces, I could deploy an application to every device. And, I could make sure that a particular website was accessible to every student from their fifteenth birthday, not a day before. And, I could make sure that any device a Ukrainian refugee logs into speaks Ukrainian. And, I could remove any bloatware. And, I could make sure that when a brand new laptop is drop-shipped to a teacher's home address directly from the distributor it will automatically configure itself with everything they need the second they connect it to their home Wifi without me even having to touch it. And, I could apply a photo-of-the-month to every device, even overlaying it with the appropriate school's logo. And I could disable (or force enable) any unwanted hardware or software features on any device. And I could make sure that every student's web traffic was appropriately filtered and, if nessecary, scrutinised.

And I could prove that all of it was working: I could prove it to staff, to parents, to governors and, when it came to it, I could prove it to the police and to lawyers. "When", not "if".

Forget schools for a second, look instead at big corporations. They are ruthlessly profit focused, but they all run Windows, Office, SharePoint, 365, etc because even though it costs money, it's cheaper overall and comes with a lot of protection, both technical and legal. Schools get that stuff basically for free, and it just works. Linux isn't there yet, not by a long shot, and no education authority worth their salt is going to take the risk of being the first to experiment with their student's wellbeing, let alone curriculum, for effectively - in their eyes - zero benefit.

To be blunt: when one of the children you are responsible for safeguarding is the victim of an attempted kidnapping that was only possible because of lax data security, no-one is going to have any tolerance for your personal philosophy about software licensing or your home-spun scripts. Ask me how I know.

Also, if your schools are letting advertisers/social media/whatever inspect student's data, that's nothing to do with the technology and everything to do with mismanagement: forcing them to manage yet another OS isn't going to fix that.

TLDR: If you want to make Linux replace Windows in schools, you first need to figure out how to make Linux replace Windows in hospitals, call centres and Fortune 500 corporations.
