Fuck all to do with the fact the baby was born at home. The article is hugely misleading - you don't check for jaundice 'during' a home birth, for a start...
It's not a cautionary tale, it's just sensationalist reporting.
Jaundice isn't always blindingly obvious but I assume it would have been clear at some point, if it got bad enough to have that effect on the baby. But unless the baby had some underlying medical problem which predisposed it to jaundice within the first 24 hours, it would not have been apparent 'during' the homebirth.
Doesn't take away from her negligence later, of course, but gaaaaaah.
