They're trying make switching to Intel less appealing when upgrade time comes. Until 12th gen, they didn't seem to view that as much of a threat. Now it apparently is. Competition is good!
Seems correct. ASRock already allowed 5000 series CPUs on their X370/B350/A320 motherboards with a beta BIOS released in 2020[1]. AMD told them to stop[2]. That beta BIOS was never officially released.

It’s not that AMD is good and Intel is bad, or vice versa. It’s that only Intel is bad and only AMD is bad.
What we need is a healthy back and forth competition between both the companies (and some ARM sprinkled in as well).
