False equivalence. Linux makes it hard, Windows makes it easy. I bet the number of zero days they have in stock is an order of magnitude smaller for Linux. If you're a spy and you have to run a maze of lasers then what you can do is more limited-- maybe steal the big diamond or something. With windows you can set up a whole tea-party and pee on the carpet on your way out.

One other point: If you run any kind of computer controlled equipment, you will know that the manufacturer designs it for specific computer platform and then moves on. Lots and lots of PC's are stuck on XP because the equipment they are attached to has no drivers for anything newer. Or the app that collects data can't tolerate anything newer. This is partly the fault of equipment makers who should provide a guarantee of a certain number of years of support for new OS's, but mostly their fault of choosing a PC as the base for something that has to be reliable. If I see such a device I say, "You know this only has an operational life span of 10 years no matter how long the rest of if would keep working". Salesmen don't like this. If it's not some unix box, there's no hope. Of course equipment manufacturers won't do that because unix hackers are harder to come by and cost more.
