If you read the article, in the security screening application, workers (at least some workers) preferred using the EEG system to screening bags manually. And if you can screen more bags in less time that way, isn't it better for everyone? Even if it doesn't result in fewer working hours because employers are exploitative either way, it's fewer working hours doing a mindless, repetitive task.

EEG-based systems that can help workers be 10x more productive at some image-recognition tasks, or that can provide real-time feedback on stress and focus to both employees and their managers, are now in pilot projects around the world. But whether or not it's ethical to directly monitor worker's brains is still an open question.

Robotics experts from industry and academia offer the most detailed and nuanced understanding of Tesla's humanoid robotics program that we’re likely to get outside of Tesla itself.
