If you're an ad based tech company, I imagine earnings are down as consumers will want to tighten the belt. If you sell software or hardware, business might also be suffering as clients may not have the funding this year or enough people in the office to do project management/training on any new tools.
And James, Amazon already has like ten warehouses where employees got sick and they did a quick shutdown/disinfection. I'm not saying they took proper measures, but they are moving quickly and probably banking on the unemployment surge to keep the warehouse workers from doing a walk out.
