Apple don’t post video montages of their security footage online and ask people to look at the faces of the shoppers and see if they can read some meaning into the lack of emotion on their faces.

When you enter an Apple store you are trusting Apple implicitly with your safety and security during your visit. That they might take security video as part of that is a reasonable component of that trust relationship. Being forced to participate as a model in an art exhibit by a random third party with no relationship to Apple violates that trust. It’s no wonder Apple would have a concern.

It’s not remotely comparable to security surveillance, and the artist doesn’t even seem particularly to be trying to draw that comparison, so I’m not sure why people are seeing this as about ‘always being on camera’.
