I think the technology confuses two things:
1. Encrypted traffic between device and wireless hotspot
2. Restricted access to the wireless hotspot (you need a password or it won't give you service)
I want to allow anonymous access, but let the traffic be encrypted. Is there a technical reason why this is not implemented?
I'm very sad by the culture (and moreso, the legal necessity) of restricting wireless access. I want to share, and have at times relied on anonymous wifi to help me get home.
