I wouldn't condone the crime against you if you used a weak password any more than I would with a celebrity (whom I honestly have zero respect for in most cases--I don't even recognize most of the names mentioned in conjunction with this).
If a system has a wide-open back door and it gets exploited, you can certainly give the system owner a hard time for being stupid (see: Target), but that doesn't negate the crime any more than forgetting to lock your door makes it okay for someone to steal your TV.
The nature of this particular crime is also notable, in that it's not just a reparable or ignorable theft but an irrevocable violation of privacy.
Well, I think some balance is needed when talking about this issue. I think what the person you're replying to really meant is that the person making a weak password should accept some responsibility for this incident occurring because if you don't protect yourself, you're asking for it.
All those celebrities with easy to guess passwords don't deserve to have their stuff stolen, but they do share a bit of responsibility. I don't see how you could argue against that at all. It's important to realize what kind of world we live in and be prepared for all the bad stuff out there
