Anyone can put together an argument for or against something by picking favourable samples. Many companies have their own reasons for asking employees not to WFH. Apple for example would find it impossible to keep new products secret if employees developed them at home, you can imagine, not to mention the amount of money they spend on the high tech glass palace they built. As for Musk in particular, I am sorry he has lost his mind. He spend 44billion dollars on Twitter and he is now destroying it.
