Yeah, maybe folks have a problem with that, but the artist certainly only highlighted already creepy-ish things that we accept all the time (companies tracking us, and the lack of an expectation of privacy in public places).

If what you’re saying is true (which I highly doubt, given that he was tampering with computer equipment that didn’t belong to him), then the laws need to change so that we can prosecute people like this. I absolutely do not want to live in a society where people can install malware on computers in public spaces to spy on me. I don’t care if it’s for advertising or some self-serving “art” project.

Apple consented to his usage of the computers within the store...they actually put them there for the purpose of being used.
