In Android you at least have the choice to run a fully open source OS and open source apps, albeit with some driver blobs.
With the exception of the blobs, everything on Android is auditable.
Meanwhile very little of MacOS or iOS is auditable.
Personally I do not use or trust any of the above, but if forced to choose Android is worlds ahead of iOS in terms of publicly auditable privacy and security.
You cannot form reasonable confidence something is secure unless it can be readily audited by yourself or capable unbiased third parties of your choosing. This means source code availability is a hard requirement for any security claims. Even if you had teams de-compile everything you could never keep up with updates.
Not all open source code is secure, but all secure code is open source.
