curious that item zero is missing.. for specific example, long ago.. Brazil was in the middle about modernizing using desktop computers, language translations, support, and a large dose of polarization about depending on American products. So many kinds of Office software were being tested, including of course the MSFT products. This story is from the late 90s.

One day, as much as I am aware, the entire national phone company of Brazil switched to using MSFT Office only, by decree from upper management. Why? much later, some correspondence between upper management / C-Suite at the company, and Brazilian attorneys hired by MSFT to negotiate, showed large, opaque payments, long-term discounts, and added support services, in exchange for changing to ONLY MSFT Office products. The change did in fact happen.

Use your own brain and understand that MSFT has able legal and business teams, hired in the target country, that have large incentives based on closing sales. Those sales are closed using negotiation language and incentives that are appealing to the C-Suite and their banking and legal partners, period.

I do not see this reality reflected in the too-neat summary of drivers there.
