I'm sure I'm not the first person to raise this concern but when tech improves to the point where there's a better option to USB C (or USB C is holding back other advances), are we going to have to wait for legislation to catch up before we can adopt it?
"A 10% additional tax shall apply to the sale of any portable device. The tax will be reduced to zero if the device uses the most common charging port in the year the device was sold. The tax is reduced to 5% if it uses the 2nd most common port in the year it was sold."
That means any big industry effort to move to a new port will, when it gets more than 50% support, will immediately get everyone else to move over to save money. And people can still use custom/niche ports, but they'll take a hit to their bottom line for the privilege - but it'll be worth it if the utility of the better port is good enough the user is happy to pay a premium for it.
The fact the tax is determined at the end of the year means manufacturers have an incentive to work together on standardization even after devices are in the hands of consumers. For example, Apple could maybe open up lightning to other manufacturers and save a lot of taxes on devices already sold in that year, if they could make lightning the most popular in the year.
