This is what's happening with open source hardware. For example, VESC and ODrive both quickly had knockoffs in all the usual places. The maintainers were somewhat understandably irked by this, but if you ask me it's exactly what should be happening. Maybe the issue was the knockoffs not complying with the license or not giving credit, but if that's all good and proper, and we should check as the end buyer, it's a net benefit to the consumer.
