Why would anyone say that WFH has a bad/lower productivity? Engineers and managers are motivated to report high productivity (as long as it's inevitable) and since it's hard to measure it's easy to fake. I noticed that some of my colleagues do almost nothing since their supervisors are not checking. I definitely work less and am less productive, too. At least that's my feeling.
