The ethics of "stealing" a WiFi connection

Network security firm Sophos recently published a study on what it terms WiFi "piggybacking," or logging on to someone's open 802.11b/g/n network without their knowledge or permission. According to the company's study, which was carried out on behalf of The Times, 54 percent of the respondents have gone WiFi freeloading, or as Sophos put it, "admitted breaking the law [in the UK]."
