I mean, probable cause is already sketchy enough, what Apple doing is beyond the pale.

Why? Police use informants to obtain probable cause regularly.
Keep your photo on your device and the software doesn’t scan it.
So yes, there’s nuance here. It’s very unfortunate that Apple didn’t engage with the community first, but that seems to be an institutional blind spot.
1. Software running on Apple's cloud scanning for content.
2. Software running on local devices scanning for content uploaded to the cloud.
3. Software running on local devices scanning for local and cloud content.
These must happen gradually to shift the overton window. Apple is progressing this.
In other words, especially in this age of trillion-dollar megacorps, when private companies enact policies and procedures which skirt the constitutional rights US Citizens have, its tantamount to these private companies looking at centuries of judicial, legislative, and even human rights research and development, and saying "we know better". Apple is an angry toddler; not a responsible adult.
Apple does not, generally, equivocate on changes like this. But the chorus against them, on this issue, is seriously big (I guess having Kelso from That '70s Show on your side helps, though). They need to step back on this and engage with the broader legal and ethical community. They are absolutely in the wrong here; that doesn't mean that the right course of action, for the iPhone, is to do nothing and E2EE everything. It just means that these actions are not the right ones. They locked themselves in a room, wrote up a slick algorithm, then said "sweet, this is a great solution which balances protecting our children from predators with the human right to privacy"; its Hubris. Its not that easy, and they can't do it alone.
