A lot of healthcare facilities are running EOL operating systems like Windows XP or Windows 7 because the programs they use for billing or other reasons are stuck on that version. You would be shocked at how prominent this is across most "modern" infrastructure. The resistance to change stems from a "if it isn't broken, don't fix it" mentality. Pagers are still the most reliable ways to reach a doctor, which is why they're still used, not because they're necessarily the most secure.
As easy as it is to point blame at "duh boomers" the situation with healthcare in particular is much more nuanced. Though I do agree that any luddites in charge of major hospitals are not helping the situation at all.
So...Oracle is just adopting the mafia mentality to accomplish this? Yeesh.
