This is the wrong take. The latency is going to be a measure of network latency and not time to physically type. It’s unlikely that the North Koreans who can get jobs in Big Tech are awful typists. But they ARE a few thousand miles away, and it takes time for the keystroke to travel that far.
I love how the cybersecurity community consensus on this story is generally that the company deserved getting compromised for being so abusive and intrusive to their workers. www.tomshardware.com/tech-ind... Monitoring keystroke latency is an ADA complaint waiting to happen.
