The assumption comes from a general observation that most normal people don't tend to use their photo library to store legal porn (other than home made) and I haven't seen any argument for why CSAM aficionados are expected to be any less careful. There are surely plenty of apps out there for keeping separately encrypted vaults of files/photos, and I'm sure many are very easy to use. You don't have to be particularly tech savvy to know it's a bad idea to co-mingle your deepest darkest secrets alongside photos of your mum and last night's dinner. Especially when discovering those secrets would lead to estrangement, or prison. As for the few who might be doing it currently, that's likely to plummet quickly. If you think Apple's move caused waves in the Hacker News crowd, just imagine how much it has blown up in the CSAM community right now. I dare say it's probably all they've been talking about for the past two weeks.
