I'm surprised they have a problem. The likes of GM is well known to trace their supply chain down as many levels as required to ensure this doesn't exist. GM has already faced this nightmare (I'm not sure if they were sued, or just got tired of protests) and takes care to ensure that they know who buys what from who all the way down. GM isn't a big tech buyer, but they are big enough to be worth changing your practices so you can sell to them. GM isn't the only company as well, just one that I know of from publicly available information.
