This whole article is pointless. Of course it doesn't make sense for Vodacom to exit the DRC, just because a new competitor is/might be entering. Irrespective of all other issues, mobile operator licenses are few and far between, and with most markets approaching saturation, Vodacom would be stupid to exit now. Operators from around the world are dying to enter such immature markets with lots of potential. Vodacom DRC already have an established network, they understand the market, they have significant market share (they are the biggest, or second-biggest?), they have existing retail distribution points, they have all the infrastructure and systems in place.
Why on earth would they want to run away because of more competition? Is Orange such a big name and so intimidating that competitors quiver at the very mention of their name?
I vote this a poorly thought out article, or an article with big gaping holes, failing to provide good logical reasons why Vodacom should even consider exiting.
