Good, they were bought out in 2006 and no longer exist.

I assume you mean AMD, and I also assume you didn't actually read the article.

The AMDGPU driver was never designed for cards before Polaris (GCN 1.4). The specific card in question, a R9 M380, was released in early 2015, and in 3 months, will be 10 years old.

The bug listed only exhibits itself on Macs, which requires a custom firmware to cope with the oddities in how Macintels boot and function, and pre-Polaris cards especially on a Mac are not well tested on AMDGPU. The bug does not happen on real x86 machines.

At no point can AMD be blamed for any of this, but Apple most certainly can (refusal to ship a compliant UEFI firmware, and instead shipping the nightmare that Macintels used during their existence).

For what it's worth, Apple's UEFI firmware is likely not compliant because they began using EFI before it was standardized. You can blame them for not updating it later, but I can understand why they didn't; it was working.

They were using OpenFirmware, the standard that EFI is built on, but their first x86 CPU was a Core 1 iirc, which had shipped with a UEFI on real PCs.
