If a certain work is done always distributed, then there is nothing to compare to. And like I said, individuals are completely capable of working and reporting from home. The real comparison is when a team works from office and then the same team switches to remote. If the outcome is the same, then Apple will continue with it won't they? Apple had clearly sent a memo to employees that they have to statistics and that they see a drop in outcome since WFH started. In the modern world, if they lied about something like that, they will get sued.
I don't see how you can state this for a whole company given the individual variances. You can state a macro statistics which is true at the macro level but not at the micro level for individual teams. And people working in companies do lie. They may or may not be sued. It takes a lot of resources to sue a large corporation.
