We asked Microsoft if a Copilot key would be required on OEM PCs going forward; […] it expects Copilot keys to be required on Windows 11 keyboards “over time.” Microsoft often imposes some additional hardware requirements on major PC makers that sell Windows on their devices […].

From what I understand, this either means that this will only affect laptops and similar devices, or that they want to force companies that sell windows PCs to sign a contract disallowing them from selling keyboards without a copilot key, with or without a PC. I think (hope?) they mean the former.
