Imagine if Microsoft sold you a secure operation system like Apple. A staggering portion of the existing cybersecurity industry would be irrelevant if this ever happened.
Not in the security industry, but my take is that basically the desktop OS permissions and security model is wrong for a lot of these devices, but there is no alternative that is suitable or that companies are willing to invest in. Probably many of the highest-profile affected machines (airport terminals, signage, medical systems, etc.) should just resemble a phone/iPad/Chromebook in terms of security/trust, but for historical/cost/practical reasons are Windows PCs with Crowdstrike.
