Earlier quoted context omitted.
You do understand why. You know that people won't work as much. Will disengage. Will cause trouble and cost you money, time, efforts. This is resources consumed. Some companies value saving resources over human decencies. This is magnified when there is crisis and resources are in shorter supply than before. There is no mystery to it, no complexity to it.
But I'm not suggesting they tell everyone the company is in dire straits and they are on the verge of getting fired. Just don't willfully lie to them on a daily basis and tell them that things are amazing and their jobs are totally secure. In my scenario, we weren't actively asking questions regularly. But they were offering the (mis)information on an almost daily basis.

It may be jaded of me but I believe it's rare to see a company with management that actually has the courage to be transparent and fully honest with its employees. I find that a good smoke test to see what type of management your own company has is probing what people in your company think about "transparent salaries" where everyone knows what everyone else makes. You'll see some enlightening responses if you're privy to the conversations.
