The EU is being itself, one more one-size-fits-all "solution" and one more sweeping regulations.

In the US we love the fact that proprietary solutions to fully optimize, and fit the technology to the purpose is still alive.

Manufacturers are welcome to install or add USB-C, and consumers are still welcome to "vote" with their wallets.

USB-C still have the problem with receptors wearing out and the connection becomes too lose. Barrel connectors better deal with that issue, not to mention they can surpass power ALLOWED by the USB-C standard. Bluetooth and inductive power is also a competitive combination. Etc...

Just my 2c
