No one deserves to be hacked, but there seems to be a clear lack of discretion involved here. There's something to be said about public conduct of an executive. You are in a public position, representing your company and its employees. You're audience is also technically inclined by nature. Fish was antagonizing people he himself stated were of low moral standing. That's not really smart. Likewise, the amount of data stolen suggests a lack of effective security protocols too. That's also not fitting of the head of a software technology company.
That said, doxxing is plain wrong. I do find it quote hypocritical of some though. This forum has celebrated the hacking of others deemed vile to the masses before, but this is somehow bad? No. Doxxing is bad, period. I don't care if you're a hacker, you don't deserve to get doxxed. We have legal systems to handle bad behavior, not vigilantes. In essence, we, as a community, have fostered and sheltered these bad elements because we've either shown support or indifference to similar acts in the past. We're part of the problem.
