"Lots of assertions,"
Not hard to go validate them via Google. All those claims look correct to me. You can get pedantic and argue that a Linux distribution isn't a fair comparison - but as stated - Windows has fewer vulnerabilities - is entirely correct - at least versus say Redhat and SUSE. Ditto the rest of it as far as I can see. Do feel free to provide factual examples of any actual errors ?
There is a list of very specific factual examples. Unlike your very poor opinion piece that you link to that shows that you are so far out of the mainstream as to be an utter irrelevance. "using a blend of Apple front ends and Linux back ends" - you won't find many FTSE 500s doing that.
