Not the GP, but I think they were getting at US facilities being a somewhat more attractive target than Italy's. This is due to both political reasons and simply having more healthcare targets to go after.
Possibly more attractive, although ransomware folks seem to like soft targets.
US healthcare is hardly a panacea of security, but they do put resources into IT. Most of the ransomware targeting seems to be seeking out softer targets, underfunded, etc. I'm not sure US healthcare is immune, but I'm also not sure they're as obvious a target as far as being easy to break into / likely to get a payout.
If it's not just utterly sociopathic organized crime, it could be one of the many, many people whose loved ones had to be taken off life support because of insufficient medical supplies and personnel.
I can't imagine that most people would respond this way, but it only takes one or two unreasonably angry people with the right skillset.
