It has obvious advantages, but the way it went no further than mini\micro-usb in design department shows it’s flaws even more.
The death of connecting parts was always a concern, and short, smooth format without any kind of a clipse fixation makes it fail to connect after a while like any other with the same production quality.
The overuse of it nowadays leads to bigger failure rates because you now can use cords interchangeably, so these connectors wear off faster than before (not to say your devices have faster charging times and higher discharging rates, so the plug\unplug routine is generally more frequent nowadays).
Your go-to universal cord can charge your phone, earbuds, vape, notebook, video-converter, beatmachine, microphone, gamepad etc. And unless you have a dedicated cord for each one of those, you’d experience them breaking up at surprising speeds.
The two-sided design is it’s crowning jewel, but I could’ve traded it for some better one-sided longer design with some sort of a lock instead. Some DP cords I have have a pair of teeth that can secure the connector in the hole, with a button to release it. It is not possible in Type-C I believe.
Big Cord bathes in cash as we speak.
I’m also one of the people who rarely has any issues with the connectors themselves. It’s always the cable which breaks close to the jack, not the connector. Also sits super tight in my phone that’s half a decade old… I’ve destroyed usb-c connectors though, by accident and with some force involved. And the cables have different quality, yes. Some are fine for many years, some are cheap e-waste.
I mean they probably don’t have any long protrusions or snap-in mechanisms, because today’s phones are very slim and other gadgets are tiny as well, so you can’t have a large connector with robust snap-in mechanisms. (And those tend to break as well, especially if they’re flimsy like the ones on network cables.)
