Eidetic memory and follows you everywhere and can transfer all those memories perfectly to any number of other people? Yeah. It's like super-stalking and it's obviously horrible.
Stalking per se is mostly only illegal because it becomes harassment and bothers the victim. This kind of monitoring is entirely unobtrusive. As the response to the original tweet illustrates, most people aren't even aware that it is happening.
The information is being used to conduct asymmetric psychological warfare. The notion that it's harmless even if never outright abused where we define abuse as use for other than its intended purpose, is false.
Being subjected to constant sensory input and trickery from dozens of teams of experts on consumer psychology is bad enough when they haven't also been stalking and recording your every move.
Caveat emptor becomes an absurd position when the power imbalance is so great. Massive data collection and mining needs to be reigned in. The fact that it's not obvious people seeking to trick you by any means necessary are recording you everywhere you go does not make it OK, at all. Surveillance capitalism is way, way over the line, has been for some time, and just keeps going farther. That they're good at keeping you from realizing you're under surveillance is no defense whatsoever.
Complaining about warfare that is asymmetrical solely due to the incompetence of one side does not elict any sympathy from me.
Consumers do try to aggregate data for the equivalent of "massive data collection and mining". Most just don't care to pay for something that is not wholly controlled by a storefront. Generally, producers are more likely to understand the ROI.
