USB-C is a misnomer. There are actually about 10 different variations, which all conform to the same physical port constraints, but have drastically different behaviors in terms of charging, data transport, and more.
By mandating a USB-C port, I fear we’ve created a pointless monopoly on the design that will stifle future innovation. Is USB-C the “best port in the world”? It’s 2022/2023, the answer may be “yes”… but MicroUSB was “the best port in the world” in 2007-2008, and its downright awful now.
Spectrum is different as it’s a physical medium that the government regulates to ensure the flow of information within that physical medium. Thats more akin to water management or other physical resources, and outside the scope of incentive management for innovations sake.
