Privacy

I don't think paranoia about the connection standard was the goal here. It seems more likely to me they wanted to increase awareness of the fact there are FAR less obvious (and absurdly easy) ways for governments to spy on citizens than Flock's installations.

Even if the goals of the government for installing such hardware are above board, they aren't known for being the most mindful of security so these systems can often be hacked and abused by malicious entities. It's something that really does need well thought out limitations set.
