The difference is that lots of different companies can share the burden of implementing all that in Linux (or BSD, or anything else) while only Microsoft can implement that functionality in Windows and even their resources are limited.
Very little healthcare functionality would ever need to be created at the OS level. The burden could be shared no matter if machines were running Windows or Linux, they’re mostly just regular applications.
Not talking about the applications - those could be ported and, ideally, financed by something like the UNDP so that the same tools are available everywhere to any interested part.
I'm talking about Crowdstrike's Falcon-like monitoring. It exists to intercept "suspicious" activity by userland applications and/or other kernel modules.
