Refusing to put pieces on the field means the other players can move without your input. They did, and now whether the OS on my machine is open is somewhat irrelevant because the things that provide services I care about won't talk to it unless I'm running closed-source blobs they control.

Hardware and firmware are bigger problems, as per cryptographic signing and legal framework to prevent breaking these solutions.
