Part of it could be due to the EU legislating USB-C for charging on quite a few consumer products. Shipping a charger, let alone a proprietary charger, is rapidly starting to become a con rather than a pro.

And USB-C is starting to become dirt-cheap to implement on the device side. 500mA @ 5V can be done without any controller chip whatsoever, and you can do up to 3A @ 5V without active communication. It's just easier to use USB-C than it is to mess around with a custom power brick!
