Again, let me walk you through this.
If a new proprietary connector is introduced, a complete new ecosystem is formed.
There are lot of different people that need a lot of different accessories for this new charger connector, like extension cords, car adapters, travel kits.
1. If the connector is Apple-proprietary, then only Apple can sell and profit from these needed accessories. No competition. No price comparisons.
2. People are FORCED to buy new, instead of reusing the stuff they already have.
In my book that is "Corporate Greed". Does that make sense?
