That may be true but it's probably more of a case of the difference between the "Maker's Schedule" and the "Manager's Schedule"[1] - i.e. managers probably don't realize how much distractions or interruptions are bad for "maker's" productivity because a manager's day is mostly distractions or interruptions.
Facebook, led by a (former) dev, has gone all-in on open plan offices - which is a direct counterpoint. That people at the top call the shots is tautological.

As another comment[1] pointed out it may have been founded by a developer, but it was one who never worked anywhere other than the company he founded and grew. Things that work well for a company of ten or twenty don't necessarily work best when it grows into the hundreds or thousands of employees.
i.e. he isn't making the decision as a developer, he's making it as a manager and the comment you were originally replying to was suggesting "for management cost and control would be more important considerations." [Though I'm not sure I entirely agree with that, as pointed out in my own reply to that comment]
