Given that the CIA recently bragged that they were able to put spyware in iOS apps because they have somehow exploited Xcode on developers' machines, one has to think about the implications of downloading executables from companies that are complicit in spying.
Just because I do something safe e.g. I compiled the compiler myself, it is the larger implication of everyone else not doing it right that is the concern.
