The 1:1 matching and the porn detection were separate capabilities.

Porn detection is called Communication Safety, and it only warms the user. If it’s set up in Screen Time as a child’s device, someone has to enter the parent’s Screen Time passcode to bypass the warning. That’s it. It’s entirely local to the device. The parent isn’t notified or shown the image, and Apple doesn’t get the image. It’s using an ML model, so it can have false positives.

CSAM detection was exact 1:1 matching using a privacy-preserving hashing system. It prevented users uploading known CSAM to iCloud, and that’s it. Apple couldn’t tell if there was a match or find out the hashes of images being evaluated.

Many people misunderstood and conflated the two capabilities, and often claimed without evidence that they did things that they were designed never to do. Apple abandoned the CSAM detection capability.

On iPhones and iPads there are several technologies available for monitoring and filtering network traffic. Filter network traffic from the Apple Deployment Guide has an overview of the technologies and their trade-offs.

Mister Softee is headquartered in Runnymede, NJ so the east coast association makes sense. It’s a franchisor so there’s trucks in 18 states.

The Wikipedia article about them says the song is titled “Jingle and Chimes”, and it’s based on “The Whistler and his Dog”. There’s lyrics too!

Apparently it was adapted to “Did you ever see a lassie?” which has much brighter and simpler lyrics than the original, which is very dark.

It reminds me of O Du Lieber Augustin. And it took me a really long time to figure out that title… I thought it was some well-known nursery rhyme melody, but it’s a 224 year old Viennese tune.

Yeah, Mr. Softee in San Francisco uses the same music. I don’t recognize it from anywhere else. It sounds like a music box, especially because many of the notes don’t hit the beats.
