I think it misses the point entirely. Being able to define MS software as malware won't make users stop using it. Even if Windows was way worse than it is now

I think it misses the point entirely. Being able to define MS software as malware won't make users stop using it. Even if Windows was way worse than it is now people would still use it. Also I believe the two distros that have a shot at part of the Windows user base(Ubuntu and Steam OS) could also be defined as malware. What has to be taken in mind is that FSF is about ideals. Which may explain why they put so much emphasis on concepts as opposed to practical matters.
