“Good thing” about the adapters for the Macbook is that they will cost ~$50, so ~£50 each at an enormous margin for them. It’s a good thing for Apple……
It’s not like it’s some Apple proprietary thing, USB-C is an open standard that’s been coming for a while. The new version of the Chromebook Pixel uses it, I’d expect it to be in lots of new products very soon. I’d bet by the time the Macbook ships (in a month or so) there’ll be AmazonBasics versions of those dongles plus countless cheaply made Chinese clones too.
If anything, the move to USB-C is a step further from Apple lock-in – if your power adaptor fails then you’ll be able to buy any generic USB-C one of the right power rather than £70 for a new Apple one.
Remember when the iMac launched with those new fangled USB ports that no-one made peripherals for but lacked utterly essential features like a floppy drive? In a couple of years the old bulky USB plugs will look very old hat.
