Common wireless standards are not the same thing as a product feature/function.So? Apple has done almost nothing with Lightning in 10 years, they upped its speed to 10 Gbps in some devices, yay. The innovation argument would be more compelling if Apple actually used their control over the port to innovate. But really we don't care about innovation in ports and don't actually want changing ports every year or two. We want a consistent standard with data, power, and video, that's what we use ports on phones for right now. Could apple come up with something new?
Requiring a common wireless standard (3G,LTE,5G) hasn't stifled wireless innovation, why should a common port standard stifle it?
Governments control wireless spectrum, and governing bodies standardized the technology so disparate vendors can align in order to maximize profitability. Apple is a singular company that can make its own technology decisions regarding which hardware best serves it's technology, use cases, and customer preferences.
