I guess the idea is that each country or region has its own Google, Facebook or Amazon - Not that it all belongs to the US government.

I would also argue that they are US companies first and global companies second. Their main focus is always USA and their spirit is also very American for the good and the bad. Strategy for the rest of the world is made in the USA. All important decision are made in the USA. Most investments are made in the USA and also the profits go to the USA.

This is nor good or bad but the point is that those are not global companies.
