@Chi20 you obviously didn't think much before posting this.
As a shareholder,you get to split the 4 B with 800,000 others as you put it but as a customer,you split it the 4B with13m customers.
SO to maximise your returns,you take your share of the 4B split 800K ways,then the company can borrow and the costs/inefficiencies can be split 13million ways,you net gain is higher.
I guess if you can't win with facts,you can always pen bile-laced,xenophobic rants to distract everyone.
