EFF lost a lot of credence to me after the Best Buy case. They made this big fuss about how Geek Squad employees were agents of the state for reporting CSAM on a customers hard drive, while doing a requested file recovery. When searched, the defendant had CSAM on 5 different devices. The case was dismissed on a technicality. Never did the EFF mention this. Never did they say they were defending a gynecological doctor who had CSAM on 5 devices. Nope, it was spin city.
Now here we are. Apple has made a privacy preserving anti-virus scanner. It does not upload unknown files as Windows Defender does, it does not scan everything. It scans your photos, for known CSAM images, when you are using iCloud backups, in order to comply with the law that they must scan their hosting services for CSAM. It has a more narrow scope than an anti-virus scanner, and a bigger societal benefit.
We seem to have taken the idea that sometimes bad things are promoted through "think of the children" to mean we must oppose anything involving the protection of children. Our greatest fear in this is the government using a national security letter to search for banned ISIS memes? Let's address that slippery slope when we come to it, and let's note that we do not see Windows Defender or similar doing the same. This is great, I hope it puts a bunch of pedos behind bars.
