No, your comment was down voted because it doesn't add anything to the discussion, other than ranting about Microsoft and closed source. Do you trust not only the Linux kernel, but the people who developed your sister of choice, along with the source you downloaded it from? Did you verify that the version you downloaded and installed was the same as the version you have source access to? Did you do the same thing for all of the third party software such as your web browser, video drivers, etc. did you do the same for your mobile phone?
Also, is everything on your machine open source? Are you using open drivers, firmware, boot loaders, BIOS?
Assuming you've done all of the above, how many people do you know of that you trust to read the code and verify the above is true for them? How many people do you know that have vetted the source code of the distro you're using. Just because someone can, doesn't mean someone has, especially if everyone else thinks someone else will verify it for them.
