Hey Gregory, I didn't mean to hurt your feelings ... I didn't know that you personally know Edward Snowden and his skills and the extend to his capabilities. I didn't know that you read the entire source code of Mac OS and found no backdoor whatsoever. So, I am sorry!
I am not here to argue with someone who has half-baked knowledge of a subject because, I did my research, thoroughly, and I'm proud of what I wrote. EVERY SINGLE WORD.
I'm a decent software engineer and I know what goes on in this industry. Believe me!
Anyways, Thanks for sharing your thought. Have a nice day!
