I don't think so. It just underlines the title of the book "Careless People".

Facebook doesn't care about anything, takes no responsibility, "can't be touched", be it on their home turf or across the globe.

I think the comparison is not meant to be between degrees of horribleness between the two events, but between degrees of complicity and denial on the part of Facebook management.

The comparison is that there are two events that Facebook couldn't mentally or emotionally acknowledge their involvement in even though they were clearly involved and had influenced, not that there is moral equivalence between the two events.
