Let me fix that for you:
> Would a toy manufacturer be sued in Brazil for selling toys without a charging cable?
The answer is: Yes.
The answer is: Yes.
AFAIK, technically nobody ever deemed any cable standard enough. I am confident (but IANAL) you would win the suit if you require a USB A to USB C cable, but you will probably get sued.
Also doesn’t quite make sense why charging cables is different than any other power source. Batteries for toys, fuel for cars, etc. Seems kind of arbitrary.
I mean, it seems pretty easy to distinguish between those two to me? One set are consumables ("batteries for toys", "fuel for cars"), while the other set are long-lived goods ("charging cables").
