There were two major flaws with the rollout of USB-C, none of them technical:

To have unmarked cables. This should have been explicitly forbidden by spec as non-compliant. Today unmarked is the norm, even with premium brands. And the few ones that actually mark their cables have their own markings (which I assume is because the official logos are so incredibly bad). So now instead of wondering if the charger will work, you’re wondering if the cable will work.

Secondly, the USB-C rollout was only successful on the sink (device) side. Almost all cheap gadgets come with an A-to-C cable, and chargers and PC ecosystems are very biased on the A ports for the host side. This created an awfully ugly side effect: devices are not always compliant with even basic charging. Since C-to-C should not have live 5V line active at all times, these devices don’t charge at all. I think they’re missing that resistor that tells a compliant charger to make it live. But in either case they only work with A-to-C.
