People can be connected to reality without standing in front of each other in the same space. Social interactions are different, yes. Creative interaction is probably different, too. However, the majority of office work does not require face-to-face interaction. Video conferencing has existed for decades, and has facilitated plenty of "reality-based" interactions with people and businesses that would otherwise never have been able to work together.
The question of there being a qualitative difference does not negate the fact that a LOT of people want to stop being in offices to do work for they can do without wasting time on a commute, office socializing, meetings that could've been emails, getting illnesses from coworkers, being micromanaged, etc.
Forcing everyone into the one monolithic model that YOU believe is good will only result in annoying or driving away the people who aren't like you. So of course everyone who dislikes WFH has chosen to attack this resigning Apple employee, instead of accepting that he exercised his free agency and left Apple because they wouldn't accommodate his working preferences. That's his choice to make.
