Why is WFH dying out?

Do some employees use office small talk as a way to monitor what people do on their spare time, so only the “interesting” or social can keep a job?

Does enforcement of these unwritten social norms make for better code?

Does forcing someone to pay gas tax or metro/bart/bus fare to go to an open plan office just to use the type of machine you already own… somehow help the economy?

Does it help to prevent carpal tunnel or autistic enablement from stims that their coworkers can shush?
