Obviously you can do it leaner, if they couldn't they wouldn't be firing people. My point is that you shouldn't be trying to estimate based on the technical side when most of the head count is negotiating with record companies and producing podcasts. In any case I personally wouldn't be so obsessed with every company running as lean as possible, great way to have 5 people make 10 billion dollars and everyone else just gets to pound sand. In a healthy society companies should run fat to keep people employed, engaged, trained up, ready to fill in as a replacement, and lots and lots of vacation time.
