Certainly the burglar deserves the lion's share of the blame for what happened, but there's plenty to spread around.
My view is that if a reasonable person would have taken actions that would have avoided the issue in the first place, a person not taking those actions shares in the blame.
My bicycle got stolen from my garage a couple weeks ago. The garage was closed and locked, but someone forced the door at 4am and stole my bike. My bike was not locked to anything. My neighbor's bike was locked to a railing a few feet away from my bike, and did not get stolen. I share some of the blame here because if I had locked my bike up -- an entirely reasonable and prudent thing to do -- my bike would likely not have gotten stolen.
I think maybe the issue is because people are conflating blame with shame. No one should be shamed for stuff like this; it's a learning opportunity. I accept blame and responsibility for my part in my bike's theft, and if/when I get a new bike, I'll take better care to secure it, even when it's indoors.
If people locked bikes in garages, people eager to steal bikes would have tools to cut chains in garages. So while it is safer to lock the bike, the blame for stealing goes to whoever stole it.
And remember that "the problem" is that the attackers hijacked the accounts of people using twitter. Twitter had a duty to take adequate measures to protect those accounts, and failed to do so. The victims are the people whose accounts were stolen, and the people who were defrauded by the hijacked accounts.
That’s hobo mentality.
It’s not your pie. Keep your goddamn hands off the fucking pie.
If hackers are a known problem, a huge company like Twitter has no right to claim it was completely blindsided when it gets hacked.
Twitter is a multinational corporation with access to the personal data of hundreds of millions of users.
It has a duty of care to those users, and at a minimum it should have a dedicated team with security policies and recovery plans.
Aside from the reputational damage, an aggressive and ambitious lawyer could make a good case for a very expensive class action if those plans turn out be defective and/or inadequate.
"As long as it can be established that your possessions have been taken without your permission most policies will pay out on a claim even if your front door was unlocked or your window open."
so - as it says later "Familiarise yourself with the terms of your policy" which I guess would lead me not to buying insurance from your company.
Aside from that allowing insurance companies to determine who 'deserves blame' seems to run counter to the common perception regarding the moral worth of insurance companies.
