The .plist doesn’t appear malicious, but I wouldn’t ideally be installing random profiles like this from random places.

How to make your own:

It should look something like this (you'll have to remove a bunch of other unnecessary settings from the file to make it look list this):

    <?xml version="1.0" encoding="UTF-8"?>
    <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
    <plist version="1.0">
    <dict>
     <key>PayloadContent</key>
     <array>
      <dict>
       <key>PayloadDescription</key>
       <string>Configures restrictions</string>
       <key>PayloadDisplayName</key>
       <string>Restrictions</string>
       <key>PayloadIdentifier</key>
       <string>com.apple.applicationaccess.masked</string>
       <key>PayloadType</key>
       <string>com.apple.applicationaccess</string>
       <key>PayloadUUID</key>
       <string>masked</string>
       <key>PayloadVersion</key>
       <integer>1</integer>
       <key>allowSiriServerLogging</key>
       <false/>
      </dict>
     </array>
     <key>PayloadDisplayName</key>
     <string>Prevent Siri from Logging Me</string>
     <key>PayloadIdentifier</key>
     <string>masked</string>
     <key>PayloadRemovalDisallowed</key>
     <false/>
     <key>PayloadType</key>
     <string>Configuration</string>
     <key>PayloadUUID</key>
     <string>masked</string>
     <key>PayloadVersion</key>
     <integer>1</integer>
    </dict>
    </plist>

Step 4 within the list is literally

Seems fine. iOS tells you exactly what the profile does and it’s not hard to understand it.

Pardon me asking but since this setting is on the client, how one is sure that it is even considered/respected on the server?

Without subpoenaing Apple, it seems like blind trust to me.

If you have a working iPhone, Googles-Android based device or Windows computer around you, it is blind trust they don't surveil you, unless you permanently monitor and control their communications.

Wouldn’t one be able to verify this by placing your own MitM at your own home gateway, no?

The requests still have to go to Apple. The only way to verify if they’re logged or not would be to examine the servers themselves and the software running on them.

You cannot.

Why isn't this just an option for users to enable in Settings?

By disabling this are you hurting the ability for Siri to understand you better? Is there any negative impacts?

Edit: Sorry for asking an important question. Blocking some of the Windows spy junk causes some issues with apps.

Yes, you are.

why don't you just disable Siri?

I for one, ALWAYS had Siri disabled, until some evil genius decided Siri MUST be on, in order for Apple Carplay to work.

At Apple: "Ah, another request to not log anything, make sure you log everything."
