It very much does matter. If more people refuse to do this type of work, it eventually won't be done to the required standard. People would cut family ties and this would stop fast.

How do you know this?
This is kind of like saying "if people wouldn't murder other people then..."
"Bad" kind of work always finds bodies to fill it's spots. Boycotts of a particular business might work, but a type of work won't, especially when there is decent money on the table. And then when you start adding in people that had previous run ins with law enforcement and find it hard to get a "legit" job and get a decent offer from a place like this, they'll have no problem taking it.
Case in point: In 2007 Germany passed a "hacking law" (§202c). On its face, it was supposed to prevent black hat work. Except it very predictably also did enormous damage to security research.
