People have been working from home for decades, but that doesn't mean the in-person collaboration is suddenly outdated.
It doesn’t mean it isn’t either. We can point to numerous reasons why it’s outdated. You haven’t given a single reason why it still makes sense.
Yes, I agree there should be a flexible WFH policy which Apple has. Those that don't like the policy can either suck it up or leave.
You have a very strange definition of “flexible”.
What about customers? Do they require the same sort of physical presence? Should Apple shut down its online store and require customers to purchase products throught brick-and-mortar stores? Tell them to “suck it up or leave”? Finding new customers can‘t possibly be any harder than finding top-flight electronic and hardware engineers, can it?
