For Windows users on the other hand, the success of the operating system has as a logical consequence, the downside of running on the most attacked platform on the market. The simple fact that Windows is a large and facile target, in terms of the volume of potential victims, focusing on the threat environment is synonymous with insecurity.
i think that's a very accurate statement, though having worked with both, windows and unix extensively, while i agree that if everybody stopped using windows without exception that certainly other operating systems would come under frequent attack, i don't agree that such attacks would have nearly as high a success rate. the main issue with windows security, ignoring the one or two inherent and hard-to-secure rpc exploits that they have said that they'll never fix (at least in xp, but possibly vista because windows software is now often dependent those interfaces), is that, by
default, it is configured with effectively zero security (i'd imagine this is in the interest of user-friendliness). since window's target audience is most especially too incompetent to secure their systems beyond anti-virus/firewall installation (this just tapes a piece of paper marked "please don't enter" on to the security holes), it would be up to microsoft to change this strategy, and if they made "very secure" the default, even given the capabilities for security that
already exist, the success of attacks against their operating system might drop by 90% or more. at least with vista, not that i'll touch it because of the drm stuff, they finally make it hell for any given program to run as an admin, which is definite progress.
EDIT: we'll have to see how their SDL stuff works out... looks like it's already implemented quite well in vista, from what a linux-using friend has told me.
now having read the whole (well, most) of the article, i don't think many people will dispute the validity of his argument, given the grounds on which he's chosen to argue. even those linux and mac users that do care about seeing the downfall of microsoft tend to refer to it in terms of "50 years from now", or "when hell boils over", both of which are, estimatably well outside the immediate future. i don't know about the mac users in this regard, but many linux users just want to be left alone, which, at least for the users, puts their operating system out of any intentional competition for "highest market share"
