It's probably far worse with Android users that Google is not disclosing. I'm seriously considering changing to Apple after this. Not that its secure but that they are willing to go to this length to communicate it.
> I'm seriously considering changing to Apple after this. Ironically that may be worse for you. iMessage is probably a critical step in 60% (or more) of these exploits, and the various unicode/pdf etc rendering engines are responsible in many exploits. Android's open-source nature likely means that a lot of these things are found by security researchers first. Don't forget that zerodium still pays more for an android…
That variability is a double-edged sword. Manufacturer-added Android bundleware is notorious for being shoddily built and could easily represent added points of ingress.
Which is why I wish it were practical to replace OEM Android versions with GrapheneOS/CalyxOS or similar on the latest devices, similar to how a cutting edge PC can run one’s choice of Linux. As long as more secure or at least more standardized Android distributions can only run on devices with some age on them, their popularity will be limited even among the technically inclined.
