Their marketing is funded by their dominant profit margin; before, people think market share equates to higher earnings, but apple shows that even with a small market share you can have a dominant profit margin and earnings, which is what really matter.
A most truthful argument. However I think that in relation to the OP its important to ask Cui Bono. This is most definitely to the benefit of apple and its shareholder, and so reflects less value to the overall population of technology users.
Assuming you don't want to get into the hocus pocus circular math of trying to figure out the value of how Apples profitability is driving competitive innovations in the greater share of the market(i.e. there would be no Microsoft surface tablet today without the ipad)
