Security is in a way orthagonal to privacy. A product can be secure from malicous attack whilst still leaking information to the Operating System provider, unless of course you don't trust the provider of your OS, in which case you're completely stuffed anyway :) Microsoft have made a lot of advances in the security field and have a generally good relationship with the security community. In contrast, I would perceive Apple as having a less good relationship with the security community (they're very secretative about what they do, they've taken actions like revoking Charlie Millers Dev creds for pointing out vulnerabilities). Linux is of course not uniform enough to e able to assign a single value to it but there are some potential concerns about their view of security bugs as just being like any other bug...
