Strikes me as an internal matter, frankly, I don't have a dog in this fight. I'm cynical enough to think that sunk costs on their enormous (and admittedly impressive) space donut is playing a role here, but it's their company to run, and it's the employee's jobs to negotiate.
I decided years before the pandemic that I didn't want to go into the office anymore, and plan to stick with it for as long as I can.
Its company's policy, they wanted to work there in the first place.
Nowadays people are complaining about everything
(1) Some workers say they are just as effective at home
(2) Some higher ups believe employees are noticeably more productive in the office
Comparing the veracity of these two opposing statement, both from groups that have some claim to authority on the matter is hard. I, as an external observer, can only really judge with the aid of some secondary information. Both claims seem, on the surface, plausible.
However, if we are indeed missing some larger point, there must some data to backup claim (2). That data does not seem to be made public, as reported quarterly profits during the pandemic were up. Not releasing that information is up to Apple, they don't need to let outsiders know how the sausage is made.

More importantly, if a non-trivial # of employees believe (1), regardless of its veracity, then Apple isn't correctly communicating their reasons for (2) internally. So at this point, we, as outside observers, don't know the reasons, many of the employees don't seem to know/believe the reasons, but we should take Apple Management's word for it?
You may trust the word of one group of the other, I'm not here to question that. Such value judgements are how we navigate life. However, expecting me to believe Apple's Management on face value, when their formerly happy-to-come-in employees don't is a tough sell.
