In insurance, if this is covered, everyone can enjoy very, very high premiums. The intent of coverage on a standard business policy is clear, if someone wants this coverage they need to purchase it, it’s a readily available coverage called Cyber Liability and Data Retention.

This court ruling would make all insurance significantly more expensive.

You should look at what the profit margins are for property and casualty carriers are in the US….they are low as fuck, many lose money. Only a few consistently make money. This isn’t health insurance, all the money goes to the brokers and agents who get paid commission without the risk and competition is terribly high. It’s not like adding coverage where none is intended won’t result in higher costs to be imposed on consumers, consumers who today often choose not to insure this exposure due to how expensive it is.
