I only read to the break, but it sounds more like this is a case of someone WFH for multiple big tech companies to maximize income - someone who isn't interested in free time when they could be puling down multiple 6-figure jobs. There are several internet accounts of people working for MS and FB at the same time, pulling $200k+ from each.

The implication of a double dipper is that they're really only giving 1/2 effort to each job, which is a reasonable assumption for the average person. Most people aren't productive more than 30-35 hours a week, regardless of the number of hours they mold a chair in the shape of their ass. This seems to be a "hey, maybe the employee isn't the problem" take - that you're paying for production, and if the products targets are hit you're getting your money's worth. Now, if they're not getting hit, or the management doesn't have enough experience to know how much effort (in work-hours/work-years) are needed on a job, that's a different problem which isn't a function of the WFH laborer.

There's a difference between has to work a second job, and decides to. Some people preffer having more money at the cost of their free time.
