I know why this has happened.
A new person has just joined high up in the council. On day 1 they're sat in front of their machine and they say "Wo ist Word? Wo ist Outlook?" Then someone has tried to explain it to them and they haven't understood. Then the head of IT has been told to come and explain it and the new person STILL hasn't understood. And they hate the non Windows look, even if it works well and is cheaper, because it isn't exactly the same as they've always had.
No amount of "But this program does exactly the same job" will work with people like that.
