The Bloomberg report on Bitmain facing a US security review should be a wake up call. Bitcoin was built on the idea that no single company or government can control the system. That only works when everything is open and verifiable.
Closed source mining hardware goes against the very foundation of Bitcoin. If you cannot inspect the code or the firmware you have to trust the company behind it. That is not Bitcoin. That is centralization.
Open source protects miners. It protects the network. It protects American sovereignty.
Bitmain never embraced that philosophy and now the consequences are catching up. Serious Bitcoiners should demand transparent hardware and open design. The network stays free only when the tools remain open.
