"decompilation prohibited" - but I thought it's written in assembly?
Which means it's not compiled?
...and on a somewhat related tangent, look at how many appliances have a "do not open/no user-serviceable parts inside" warning.
Assembly language is still a textual, human-friendly language where you can give memory locations symbolic names, you use mnemonics for the different machine instructions, many assemblers have various forms of macro support, etc. That all gets "assembled" or "compiled" into the machine code.
