Nobody cares about it because unless you use IBM, or use it in some embedded use cases it’s irrelevant.
It’s irrelevant because while they would openly license it, it wasn’t open source as you think about it traditionally and would require you to cross license derived technology to the consortium, which was effectively Freescale and IBM if I recall correctly.
IIRC they have only recently open sourced and freely licensed the ISA. Even then, there isn’t much interest in it outside big iron or niche platforms.
