Microsoft has been driving users away for no less than 10 years now and nothing much is changing IMO because Windows is what most people think of as "the computer". Non-technical users think they have no other choice, they shrug the defects off and try to get their job done.
Though the article kind of piqued my interest by claiming that Microsoft "is in panic" -- any proof that they are indeed bleeding users more than what is deemed normal?
I have noticed people around me get recommended Linux Mint and being happy with it but I'd think that's a minority; many offices rely on bespoke local network setups with printers and scanners and people putting files in shared directories and what-not... modernizing that and making it better is no easy feat.
EDIT: Oh, and as other users are saying, Linux desktop is absolutely not going to eat Windows' lunch. There are still too many confusing things there, and "you can hack it and make it your own" appeal to an infinitesimally small audience.
