After rational analysis in Occam's razor style: Apple is not forced directly by no one, they are preparing this implementation since iOS 14.3 (from recent data), this is obviously done with Apple management knowing that some governments will apply pressure over monopolistic nature of "Apple closed ecosystem" and the obvious politically correct solution is to provide a "secure" way of monitoring user behavior by labeling it "for the common good narrative".
The implementation is designed to give the users impression of "privacy" and in the same time to remove Apple from the loop of eventual legal responsibility. The tipping point is "on device scanning" where your property is reducing the cost of the process for Apple and reassuring normalization of privacy intrusion and surveillance. This "move" creates "new business" opportunity for Apple, done behind closed doors and will send clear signal to interested third parties in user data.
Apple practically is moving in Data Broker territory, takes a marketshare from Google and Facebook in the process.
The added value is "optimization" of Apples control over services.
When the users are accepting the technological solution and are convinced that this is "privacy", implementing "perceptual hashing" and Neural Hash for other purposes is no brainer.
So to summarize: This is the defining moment for New Apple. Removing rationally thinking user base - "screeching voices of minority", implementing secure "backdoor" for multiple cases of digital policing, using "CSAM" as a politically and publicly acceptable problem, entering the Big Data Broker market with power move and reassuring that no government will be compelled to break the company for monopolistic practices.
I am done with this company, and fully understand that majority of normal users will accept this just because.
I am sharing this with hope to help the minority of Apple loyal users (like me, until this stupidity) to understand that its time to tame our collective addiction of "conveniences" and learn important lesson: Never trust your private data to a closed software/hardware company again.
Its not Apple's job to police the world and it can actually make life harder for those who have to chase child abusers/pornographers.
As for whether Apple has been leaned on, its quite possible, as Apple has in the past been leaned on heavily with even the media showing officials of various government agencies accusing Apple of aiding terrorists by not providing a backdoor.
Apple are facing fines in various countries for AppStore and other issues, facing court battles with other companies and it was just a few weeks ago Apple criticised Facebook and others for their actions in reducing privacy. Apple even made privacy a mainstay of advertising, so yes it is possible they have been put in this position.
Judgements could be made in favour of Apple, countries can offer deal on AppStore where many are investigating it with prospect of mega million fines. All sorts of pressure may have been brought to bear on Apple and we know they've had such pressure before, but with the AppStore situations and certain court actions the leverage would be there.
The best way to dispel that concern is for Apple to NOT go ahead with what so many organisations, MP's, IT specialists, media, Apple Employees etc etc. etc., suggest are concerns over a backdoor and where its relatively easy if installed on every user's hardware to modify the tools.
Just reported on the news that there are now over 90 policy and rights group to abandon their plans on this matter, let alone MP's, IT specialists, media, so some here trying to condescendingly make out that everyone misunderstands on here and elsewhere are in a losing battle, and Apple won't give you a discount!
The irony is these posters still refer to Scans and then seek to mitigate it by saying they are only hashes, as if that isn't data!
We should perhaps remember that Apple has already bent to some governments:
Apple built the world’s most valuable business on top of China. Now it has to answer to the Chinese government.
