Apple tracks you every bit as much as Google, with even fewer options to mitigate it.
The bottom line is, with Apple you can't control anything, and they mask the process for limiting data collection using dark patterns.
Also, you can't turn off Siri data collection. What you can turn off with Siri is it responding to voice commands - with the control panel being another dark pattern.
On my Pixel running Graphene, Lineage, or DivestOS, there's no assistant to collect such data.
On my Samsung, the assistant has been disabled using ADB (since the phone can't be rooted or flashed).
Apple is arguably worse, because you have no way to mitigate these issues.
