I think the parent has a valid point. The actual README says "inspired by Apple’s Private Cloud Compute".
I think it's more fair to say it implements the same idea but it is not an opensource implementation of Apple's Private Compute Cloud the way e.g. minio is an implementation of S3, so the HN title is misleading.
It's not a drop-in replacement; rather it is an implementation of the same ideas (+ some extra ones) but open source so it can be used for things other than Apple devices.
