No, I guess because it has nothing to do with productivity.

It’s usually about justifying costs of real estates or property of commercial buildings.

Big companies usually own buildings dedicated to offices for their workers, maintaining them is expensive, having everyone working from home would mean rendering their properties useless.

So they come up with all possible stupid PR excuses about it, the company I work for does the same, but we employees know, if the company openly told the truth about it, I believe many people would revolt.
