I will grant that it's a broad generalization, but I don't think it's a straw man. The implicit sales point of a lot of software is that it removes the overheard of research and quantitative looks and provides hard data. If data is not questioned and checked, then there is an implicit trust. Yes, I would agree the above are bugs, but the point is more about: 1. How did the bug get there in the first place? 2. What is the time to resolve these bugs, if they ever are? 3. A program can be used for things it was never intended to that has harmful effects. This is the basis behind exploits where software doing exactly what it was designed to has an unintended effect. It's not about universal usefulness, it's about who the program actually helps.
