In all honesty, the original question was a poor straw man for multiple
reasons:

* Basically nobody does business in 100 countries.  Level 3 only claims
  60.  Verizon does claim 150, but a lot of those are rather arms-length
  deals.  Apple has a "presense" in 97 countries.  It's a question about
  perhaps not a unicorn, but a rare albino pony only seen a few times in
  the wild!

* The companies that do business in these countries rarely have "100
  national business units".  The chance that all countries are wholy
  owned subsidiaries created by the corporate parent is zero.  They
  are parterships, co-branding deals, buyouts of existing companies.
  All of which bring baggage that affects the question more than any
  any technical details.

* Because of how these entities come to be, the chance that the network
  contains Vendor's A and B, and corporate gets to dictate anything is
  zero.  The network will have Vendors A-Z, plus a few more.  Legacy
  stuff hidden in corners from 50 different M&A activities.  Multiple
  engineering teams, in multiple locations.

* Technical people never get to decide the level of "autonomy".  A mix
  of local laws, M&A terms, and other business interests will rule.

Which leads to an easy answer.  It's better for upper corporate to
negotiate bulk deals (note I did not say one vendor) and offer standard
solutions to each national BU, so that the engineering does not need to
be repeated 100 times.  Simple economies of scale.  That said, some
number of the national BU's will not follow that advice, for perhaps
good and often bad reason.
