@feld @veronica It's not binary. For one thing, human civilization got by for millennia without every single thing we did outdoors being recorded and stored in perpetuity.
But even granting that being in public means you should always expect to be recorded, there are limits to how much privacy you can reasonably expect to have to sacrifice. To pick a somewhat extreme example, upskirting doesn't become fair game just because there's a CCTV camera nearby.
