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.
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).
Requiring signed firmware is just a lock to keep poors out.
It’s Never used for consumers benefit, not once, not ever.

It costs the ability to flash your own firmware.
That’s 100% of all signed firmware implementations.
