The vectors I fear are the potentially malicious brains behind every pair of eyes. Why do you want to see my OS (or really any of my software)? The only reason I can think of is to have access to my files, or to hijack my machine and install customized ransomware as part of the OS. Therefore, any individual who sees any part of my OS that could grant them any access whatsoever to any part of my PC is an extreme and real danger.
