My experience working in a small startup, a largish tech company and a FAANG, is that management (especially at the top) follows a highly unbalanced bimodal distribution - that is, about 85-95% of management has no idea what they're doing and in many cases are actively hurting the company. But 5-15% are actually great and know what they're doing, and can carry the deadweight along. But since they're a minority, they are completely focused on getting the business to work; the deadweights are the people making the open office decisions.
