Yeah, hell, lets let the phone companies develop their own wall outlets too! Call the electrician, we need an iOutlet!

You mean no phone company would make their own proprietary connection for profit and nothing else? Sounds great. Charging ports should not be designed by phone companies. Thats the point of this. Not to stop the development of new port.

The U in USB stands for universal, it is developed thru a non profit organization, supported by lots of differeny tech giants (apple included). Its just like how we have standards for wireless charging or wifi. When you go to a hotel, you dont have to worry if they only support "apple wifi", you know that all your wifi enabled devices will be able to connect. Theres little/no benefit to allow companies to do their own thing. Lets get everyones hands on helping develop the next universal standard, instead of working on their own.

Couldnt they have just made an EU specific model, or removed the port entirely?

I think the main difference is transparency
