For all practical concerns, downloading FOSS in binary form is not that worst compared to source code, unless you are willing to audit thousands of lines of code before compiling (and is competent enough). The exploit can even be hidden into the compiler itself, not in the source. I don't have a solution for this problem, I'm just commenting the fact that it is more complex than "compile from source" and that you have to draw a line somewhere unless you assemble your hardware from raw materials and write your own software.
