I think the cultures naturally change with scale. Is isn't a requirement, just a tendency. At least from my personal experiences, friends and read over the years this seems like a good general heuristic. I personally use it as a primary rule for job seeking, I ignore any company over ~500 people. Once they are bigger than that and their culture seems to start naturally evolving to the same stance of people being interchangeable cogs that have no worth as an individual. This naturally leads to team ownership as there is no one else.
