Suppose you are Twitter and operating in, say, {Ghana, Russia, Korea, Mexico, and Pakistan}. You're served with subpoenas and legal IP requests in each country. If you dont respond in time, your license to operate may be revoked. Each request is in the native language. How do you "scale" this technically? Can one lawyer handle these across the world? How?
Furthermore, developing tech for managing this is likely to be unnecessary as there are existing software packages already out there. Doing business across the world and handling legal issues is not unique to Twitter.
I generally agree with your response, but note that you've just converted FTEs to contractors/outsourcers and "reduced" FTEs that way. You'd have to do the same with accountants and many other country-level positions. But w2-->1099 isnt really a "win".
This seems intuitively false. Adding more people to tech domains can actually decrease effectiveness with more expense, resulting in lower profits. Obviously, there is a sweet spot, but Twitter is a basic product regardless of how many countries it operates within.
