Your position is that "selling unlicensed equipment" is a liability risk for Deye but... deliberately disabling equipment you don't even own is not?! All they need to do is the same thing any manufacturer whose stuff ends up on a gray market does: "We're very sorry and we don't know how this happened. We'll work with regulators to better audit our export shipments in the future." This kind of thing happens all the time.
