As far as I understand Apple could have still supported an additional lightning port if they really cared about it.

Per gemini for making ligthning accessories you also have to pay 4$ to apple per device that are passed onto the consumer.

I dont know in what way that has to do with colonization.

USB everywhere is nice because you can use the same charger for all kind of devices and dont have to carry multiple with you.

The different kind of specs for usb cables is unfortunate, but you can just buy the highest spec ones and only use them.
