People absolutely do care about security cameras, as demonstrated by ongoing opposition to Flock cameras. Security cameras have been widely deployed at a time when they weren't interconnected and people had to physically obtain tapes to look at the footage. The cost of engaging in stalking or mass-surveillance has lowered dramatically since, and people are strongly opposed to these technologies once they realize what the current capabilities are. The public never consented to any of this, but those responsible are maliciously framing the past lack of awareness as consent.
