"...I call bullshit on that. Maybe your average beancounter does not know or cares about difference between Windows 10 and Gnome but try to replace their Excel spreadsheets with Calc and ask rewrite all macros in totally different language and you will very soon know what exactly the costs of transition are..."
Not just macros but plugins.
Anyone that's worked in the public sector will know they often rely heavily on them. And not just limited to Excel.
