An interesting legal precedent may not be as far-reaching as the headline might imply:
Breaking in to an encrypted router and using the WiFi connection is not an criminal offence, a Dutch court ruled. WiFi hackers can not be prosecuted for breaching router security.
A court in The Hague ruled earlier this month that it is legal to break WiFi security to use the internet connection. The court also decided that piggybacking on open WiFi networks in bars and hotels can not be prosecuted. In many countries both actions are illegal and often can be fined.

The Judge reasoned that the student didn’t gain access to the computer connected to the router, but only used the routers internet connection. Under Dutch law breaking in to a computer is forbidden.
A computer in The Netherlands is defined as a machine that is used for three things: the storage, processing and transmission of data. A router can therefore not be described as a computer because it is only used to transfer or process data and not for storing bits and bytes. Hacking a device that is no computer by law is not illegal, and can not be prosecuted, the court concluded.
The key here is the definition of a computer under the law: I expect the Dutch to update this definition in response to the outcome of this case.
