Telling employees that they _need_ to be in the office on days X, Y, and Z destroys most of the utility of remote working. They even chose Monday, Tuesday Thursday so people couldn't have a four day long block for working or traveling elsewhere.
If Apple cared about flexibility, they'd do this, in order of "how much do they care":
- Employees choose if they want to come into an office at all, figuring out their work dynamics on a per-team basis
- If a number of days per week in-office is required, employees gets to choose those days
- The company chooses the days the employee comes in (which is what Apple chose)
