For some reason, some people have this inexplicable rose-tinted vision of Apple. Until they release the source code of their products, the only rational stance is to treat their software as malware.

If further evidence is necessary, any Apple device that I have owned pings multiple Apple domains several times per minute, despite disabling every cloud dependency that can be disabled. The roles of the domains are partially documented, but traffic is encrypted and it is impossible to know for sure what information Apple is exfiltrating. It is certainly a lot more than a periodic software update check. It certainly seems that Apple is documenting how people interact with the devices they own very closely. That's an insane amount of oversight over people's lives considering that some (most?) people use their phones as their primary computer.

I just opened Activity Monitor - a process called "dasd" is the 5th largest consumer of CPU time. What does it do? Apple does not want you to know. Apple also will not let you disable it. Apple will not even tell you if this process is legitimate (it is signed by "Software Signing" lmao).

    $ man dasd
    No manual entry for dasd
