I don't tend to think about the scale of companies in terms of number of employees. I'm often very surprised at how big or small a company is, especially based on their perceived size.
I also think this is a good forum to have those discussions on. Many people here either work in tech, have worked in tech before, and maybe have solved similar problems at similar scales to other companies before.
It's only natural to look at a company that seems to employ 10x more people than you expect and wonder "what the heck are all those people doing"
I think P's frustration is that saying "Wow, $Companys head count is high" on every thread is not an interesting, insightful, or discussion driving comment.
Why is the headcount high (outside the obvious)? How could it be prevented in the future? What are the ramifications of this in the future? Even as you suggest, why not respond to "What the heck are all these people doing?"
Not "Wow, headcount high!"
