Look, I'm the last person in the world to defend Microsoft but ....
End users do care. But they also have a lifetime of Windows usage and a whole bunch of Windows software. Sure you could run your Windows software in an emulator but that's just another thing for Mom & Pop to learn.
Its fine for a techie to say "I switched to Linux and its fine", but for a complete non-techie who has spent their life on Windows its a big ask.
Companies also care but it also has to make hard-nose business sense.
So when Microsoft turns up your doorstep and says ... "hey, you can have email, MDM, cloud-based file server, conferencing, calling and your old favourites Word, Excel, Outlook and Powerpoint all for $20 a month .... and all locked behind secure 2FA authentication" what the hell do you expect company management to say ? Its a bit of a no-brainer really.
In addition you are a company, you employ people. Its a productivity killer to tell all those people who have been using Word/Powerpoint/Excel/Outlook all their lives to go learn something else.
