I can guarantee you that few people have access to the Windows source to check it.
I can also guarantee you that many more people have access and have audited the source code of a GNU/Linux system.
I cant guarantee you that GNU/Linux doesnt have backdoors. But for all intents and purposes it is just plain Wrong to use windows for any security related activities.
Would you be more comfortable leaking documents using a GNU/Linux livecd or Windows?
If you think Linux has less chance getting backdoor, well, look at all the speculation we got these days. If NSIT cryptographic standard has reduced security as many people believe, then your communicate is dead.
If you believe that all ISP are cooperating with the US government here in the US, why the hell are you still using the Internet as we know it? You are guaranteeing that only an open source system will not have a backdoor while a closed source must have. Microsoft has collaboration with NSA in one way or another. Is that a secret? Most of their "collaboration" probably come from business things like military-kind projects. They might have backdoor. But guarantee is a big assumption. If you don't have solid proof then you are making false accusation.
It's like saying because your friend shakes hands and hang out with a cold-blood murder he must be a cold-blooded person too. Plain wrong, ignorant and simply stupid.
Security has a trust involved. If you don't trust your USB, your own product, then you will not get any security. There is nothing wrong with transferring things between usb and windows computer. It's fine. You can still run SCP, SSH over your Windows socket. Is that now weaker because damn MS is working with NSA as you say?
Someone give this man a cookie because we are obviously living in an fantasy.
If you think your ipod, your laptop don't have backdoor according to how MS and Intel are working with NSA, you are contradicting. Stop using the Internet and stop using anything. Then you are safe.
