The point is arguing about something when you plainly don’t understand how the UK still has GDPR doesn’t really validate your opinions in any way shape or form…
The security doesn’t matter, nothing other than Windows is used. To move to something else would cost so much that businesses simply cannot sustain that. We now have workers who have had 30 years of only working with Windows… and new workers only get Windows. Doesn’t matter what you or anybody else thinks, or says, it matters little. It is pretty much set in stone that you need Windows and Office in the UK, plus other software to make things like PDF’s and documents. You can point anyone towards anything and it just doesn’t matter… and here in the UK they don’t care about lawsuits, we don’t sue first and ask questions later - our legal system is just not setup that way. It is so difficult for other countries to understand, but that kind of approach just doesn’t happen, and our legal system takes little notice of legal issues in countries like the US.
