There is the issue about Siri sending info also even if you opted out.
I think its probably minor compared to Google's harvesting on android, and probably kept within Apples garden, but with a Corporation ( and now Fascist regime ) they will eventually choose profit or government compliance over privacy.
I've moved to GrapheneOS to avoid google, but Google seems too be closing off OpenSource parts of Android, so that Project will probably come to end at some point.
