Is coreboot/open-source firmware worth it?

So I have had the think pad x250 for about a year. I run Linux on It full time, and I am a advocate for open source software.

With that said, I was intending to run coreboot or a open source firmware and then I noticed Intel went full retard and blocked firmware that's not signed by the OEM. So is it really worth it looking into trying to find a way to get around this? I have never used open source firmware before so I really don't know the difference. Could someone give me their "un biast" opinion on this?

Thanks,
Maleldil

From what I know from hardware hacking and what I have read coreboot and librevoot are supposed to be a bios/uefi replacement that you can edit at any time to open up features that you may not have available (like how intel 1366 chips had hyperthreading but it was almost never available). On top of that, I would assume it keeps bios level hacks out of the system better since the code itself is different.
