In case of my wife, she has a private phone number only for friends & family and another one strictly official. There are many uses ,
* If she leaves her job she can give the SIM back to the company and won't get anymore calls on that
* Separate billing. Company pays for official calls only
* Switch On/off one SIM or other when required
The other use is for bargain hunters. There are so many operators to choose from. The ones with wider coverage are expensive and the others are dirt cheap . So the cheaper one is usually used for making outgoing calls when the signal strength is good. The expensive ones are used for incoming calls (which is free in India. Here calling party pays) or even for outgoing calls when the other one has poor signal.

Apple will have to improve their distribution and variety to appeal to new users. So , this trend will only accelerate
As consumers , collectively we can influence corporate behavior. If Companies feels that customers can punish them for such acts they may refrain from it in the future. The point is , the scale of the protest should be big enough for them to sit up and notice
The problem is that the govt is providing an artificial barrier to entry by other companies which protects the profits of the big pharma. Because of it the pharma companies have no incentive to reduce prices . They would rather spend the money on lobbying
