- sp332 13y agoPeople set up radios and broadcast data completely indiscriminately? I would argue that is like yelling a conversation and then being shocked that people might overhear you. (Also it only gets certain packets depending on what network you're joined to, what channel you're listening on, etc.)
- morpher 13y agoI agree about the yelling part. But, to clarify, you don't have to join a network, and you can always scan channels. Although chances are that most people around (e.g., at a coffe shop or airport) are broadcasting on a specific channel.
