Getting multiple manufacturers to agree on anything is always going to be a challenge and produce some compromises. But it's still better for the market as a whole, which in turn is better for consumers. I look forward to the chance of buying a single, universal charger with great features that will last me decades, from a vendor that may or may not be a phone-manufacturer. Apple would gladly do their worse to stop me from doing that, if they could.
I really highly doubt about the decades part. I also highly doubt about the "single charger with great features" because USB has so many optional parts that many manufacturers are unlikely to implement.
These are all the plugs USB has come up with over the years: https://en.wikipedia.org/wiki/USB_hardware
I still have a bunch of USB cables and devices at home, and I every time I have to use them I struggle to find the right combination.
Standardization is good. But in this case USB is objectively not a better standard than Apple's proprietary one.
If anything, Apple's Lightning port (and the 30-pin connector before that) are significantly more consumer-friendly than USB. Where consumers are consumers of Apple products, but still.
In the span of time when Apple only had two connectors, USB went through 3 or 4. USB didn't even have a charging standard until 2012 (the year Lightning was introduced).
And even with USB-C it's still a hodge-podge of standards with multiple optional and non-optional parts, and it's not getting better: https://old.reddit.com/r/UsbCHardware/comments/mjz2pu/usb4_a...
