Having up to date Android and iOS zero days plus the rootkit / RAT software is not something you can get open source or find easily commercially.
You might be right about not being able to find 0days that target the latest versions of iOS or Android so easily, but there are dark web markets stuffed with 0days that target specific versions, or a range of versions. Not sure about pricing, but they're typically cheaper than the exploits that target the latest and greatest.
It's by pure chance that the owner of a device is using an out-dated O.S on their phone. Others may argue it's not by chance, but by design, and that some phones can't upgrade properly and remain locked to a specific version..You know, because governments sometimes demand that phones are deliberately left unpatched so they can do interception or do ex-filtration on them?
