> This advice is akin to "don't do drugs." The devil is in the details. And the details aren't always black and white. If the details were black and white you wouldn't need a CEO, you could build a machine to do the job, but actually you can get a black and white version: Pick a wide enough safety margin between the black parts and the white parts. Now, if you make it too wide your profit will suffer. If you make it too small you run risk of going from white to black. And somewhere between those two extremes is the correct course of action to take, depending on your personal risk profile (really white? Maybe a bit gray? dark gray?), your knowledge of the situation (I KNOW that this is white vs. yeah, probably okay) and so on.
