It's mostly 1 in your examples. Morgan Stanley and Google do lots of different things, which requires lots of different people. Ford does lots of labour intensive stuff with a heavily unionised workforce. Facebook and Twitter do more than you'd think, but more importantly do it at massive scale. Medium, however, has one relatively simple website, at a scale nothing like Facebook/Twitter/Google. I struggle to imagine what they all did.
