oh im totally aware of there being a reason, it's just massively annoying because i deliberately seek out USB C stuff (which is thankfully becomming the default) and then frequently having to return it because the whole point for me is having a single charging solution and not 4 of them
The main issue seems to be lack of resistors in some devices, which leads to USB C not seeing the device to be charged as such, as it isn't negotiating the USB-PD part. USB A doesn’t officially implement a power delivery negotiation spec, it’s just always on at the charger end, with more amps possibly being negotiated if I’m reading properly.
People seem to be able to resolve this issue with a daisy chain. Devices that usually only work with A to C cables might be able to use a C charger connected to a C to A (female) cord or A to C adapter, which is then connected with a standard A to C cable to the device to be charged.
It’s probably easier to keep a USB A charger and A to C cable, but hopefully this helps put your mind at ease that there is a rational explanation.

The Reddit post below actually explains how to work around the problem as I mentioned above:
