That's what a philosophy is, gives you some general guideline and you have to use your thinking to figure out how to apply it in specific circumstances. It does not substitute that thinking neither does it prevent stupid choices, it helps guide you in a higher/strategic level. It is not responsible for people making stupid decisions.

Sure but my point is that the Unix philosophy is so ambiguous that it leads to more confusion than it helps.

Stating it in a way that makes the ambiguity obvious - "don't make your program do too much" - reveals how little value it contains.
