I would say that, in my opinion, the company's "heart and soul" has declined. Admittedly, this is highly subjective, and depends on what one does and does not value about a company and it's moral, as opposed to financial, compass.
But, the fact is, we simply cannot know how Walt, or anyone else would have handled this absolutely unprecedented pandemic. I can romanticize past leaders, but they were also a product of their times and context, so it is just conjecture and fantasy to imagine that they could have done anything differently, let alone better.
