Apple absolutely does not fix bricked systems out of warranty, regardless of cause or fault. Certainly not two years removed from the warranty. They can, in very rare cases, get bricked by failed updates. It’s not totally unheard of.

“Unequivocally wrong” is highly debatable. You may feel that way but I don’t. I’m not defending anyone, I’m just providing a reality check on how things work when you buy a product from anyone.

I think the only thing framework did wrong is fail to provide a BIOS restore fallback function, which my desktop motherboard has, but not every laptop has a feature like this.

For one thing, any conclusion that a BIOS update failure is automatically Framework’s fault is a big jump to conclusions. A BIOS update has a small risk of failure with any device. Find me a motherboard manufacturer who will bail you out outside of the warranty period and I’ll do three cartwheels for you.
