But you're not punishing the people who live in the ghetto, you're punishing the people who are visiting those who live in the ghetto.
If you feel IPB has done you wrong and in turn, you refuse to help them - fair enough.
If you feel that the people who buy IPB and use that as their software have it coming and should instead use something else, so you refuse to help them - kinda fair enough.
But you're especially punishing the innocent visitors who visit the sites of those people, who had little to no say in which software is used on the websites they visit Sure, you might hit the other 2 in the process as well (after all, having your website hacked is not great publicity and being the developer of the software that got hacked isn't either), but those visitors have issues with their accounts, might have other accounts hacked as well because they use the same password / email address on other websites, or might be targeted by spam because those email addresses get sold. You're hurting the innocent people the most in my opinion, and I don't think that's fair. That's all.
