Signed firmware doesn't cost anything, so I'm not sure what you mean by "keep the poors out." Signed firmware has a very valid use case for preventing supply chain attacks. The only time I have an issue with it if there's no way to make your own signed package or bypass the requirement.

It costs the ability to flash your own firmware.

That's 100% of all signed firmware implementations.

These checks are usually at the application level, so flashing via telnet/SSH still works. It's generally not like TPM where the boot will be blocked if the signature doesn't match, and in many cases, systems with those protections have a way to set your own keys (e.g. like with GrapheneOS on Pixel phones).
