Because poorly secured CORPORATE wireless networks enabled rogues to steal more than 40 million credit card numbers (a number that should be verified) means that all wireless connections have to be "secured"? And not doing so is a, what, crime? How about people who actually share their wireless access point? What about hotels, cafés, restaurants who share their wireless access points with customers and the neighbourhood? Or people like you and me? 
What really bothers me is that there are already enough idiots out there who claim that sharing a wireless connection is something illegal (see for example comments at The Inquirer). The truth is that most telcos are involved in illegal activities.
Quite frankly, I would not trust a "security" firm which counts on FUD.
