As someone much older than you with a BS in Computer Engineering, graduate of 1992, I look forward to the grey hairs you find yourself with thinking that programing anything on this scale is always such a simple matter.

I for one believe that SE does their very best to be above board and honest with it's users, more so than some people in real life surrounded by real life events. If you choose to distrust them, please just leave. To attempt to 'call them out and demand such an answer' make you look silly.
