There are tools like this for tracking git commits and velocity (that I’ve been on the receiving end of). It probably makes less sense in that context, but if your job is a repetitive task, I don’t think it’s necessarily abuse or dystopian to track it.
Monitoring bottlenecks isn’t a bad thing. They probably could have chosen an example where the solution to the bottleneck didn’t involve berating a low performer (e.g. adjusting the line to add another station or similar)
