Clearly, end customers are committing to a certain mobile telephone network, to the detriment of its competitors who do not win that business. This is where competitiveness comes in- between companies. When business activities are complimentary, all parties involved can earn a profit. When inter-company business activities are competitive, some earn a profit and some do not. Just because one company gains and one loses, does not mean that profit is a bad thing.
