This was my first thought too. The last generation of activity tracking, while still dystopian, was a little different at least in that it was mainly statistical. So action-wise, it might point managers at "potential problems," but doesn't make its way into a performance review (e.g. "your mouse only traveled 81.72 screen-miles this quarter, 2 standard deviations below the mean, while you also scored the lowest on number of keystrokes with vscode as the active window..."). If a manager really wanted to summarize exactly what was done they had to spend an almost equal amount of time to watch. To some degree, this alleviates that.
