You're not entirely wrong. For a proprietary, closed-source, limited-access system that Apple has complete control of, it's surprisingly vulnerable and slow to be patched.
It's pretty much completely wrong. Apple invests more on this problem than almost any vendor in the world, and no vendor with a comparable footprint fares meaningfully better than they do --- Google surpasses them at some problems, but vice versa. The problems we're dealing with here are basically at the frontier of software engineering and implicate not so much Apple as the entire enterprise of commercial consumer software development, no matter where it's practiced.
It's fair to criticize Apple. But you can't reasonably argue that they DGAF.
