You're right. One of these forces is how in a sufficiently large organization you're practically guaranteed to attract a critical mass of bad actors, people with rare but extremely harmful personality types. In an open culture, these bad actors can find each other and coordinate, creating massive problems for the whole organization. Traditional big companies are robust against these bad actors --- unfortunately at the cost of many other desirable characteristics. Smaller companies (maybe up to 10k headcount) can get without the necessary safeguards because, due to their small size, they don't attract a critical mass of rare but extremely harmful personalities. Google tried to remain an open, high-trust place well beyond the point when it became obvious that the company had attracted exactly this sort of toxic element. Now the company is paying the price.
