China still makes most of the RCs. I have no idea what these firms look like over in China, but I don’t think they’re like the manufacturers in Latin America hiding in jungled and churning retail barrels. If these factories are big enough to be producing and selling large quantities on the dark web (and clear web! You can find several stores openly selling them on google lol), then there’s major capital behind the operations somewhere. Either that, or someone on the assembly line has very nimble fingers.
