Earlier quoted context omitted.
> without your consent The author mentions getting consent from Apple employees on multiple occasions. If you asked me if you could install spyware on my computer and I said "yes", then of course it would be legal.
Bull. Shit. "We got situated in the store, double checked with an employee that it was ok to shoot video" There was no consent to install software onto their computers. They just tried to find some consent loophole.
Higher up in the article when the author first introduces the software, they say this line:
> I just had to double check with an employee.
Very vague, yes. It's entirely plausible that the author deliberately hid details in that discussion, or just unintentionally communicated it poorly. But in the absence of any evidence towards that, I don't think it's unreasonable to assume that the author is telling the truth.
