Isn't the use of USB-C promotion without at minimum basic USB compatability disallowed?

I have a few devices which have a USB-A to barrel plug, but they do not advertise anything and afaik that is perfectly fine. And they also only work with a normal USB charger, not the fancy ones.

It's called a step drill bit. It's basically a hole saw but for metal.
