Agreed, firmware security by chip manufacturers has been underwhelming to say the least and we can blame them for that. But in this specific instance I still don't see the benefit of a fix for consumer usage. Companies have a responsibility and accountability toward their users, so a fix is due, for personal laptops/PCs the threat is toward the owners themselves (activists, diplomats, journalists, etc.). The latter do not buy second hand equipment, and if the firmware is compromised while they own it, they are already in danger.

Consumer usage is not really concerned by the attack scenario of this vulnerability from what I understand. The prerequisite is to have access to the bios so it's already game over at this point.
They are bad at writing software and firmware support is sketchy. That second point is technically the motherboard vendors fault but it could be due to confusing design and documentation on the AMD side. Hardware-wise they are great AFAIK.
I'm not saying this is a small issue and nothing should be done. I just noted that the issue is not as big as some other hardware-based vulnerabilities we encountered in the past. And every threat model calls for a corresponding counter-measure.
