Probably the best externally-visible example of that pressure campaign is this 2019 open letter to Facebook signed by US AG William Barr and UK Home Secretary Priti Patel. Along with some dude from Australia whose name I’ve already forgotten. https://www.justice.gov/opa/press-release/file/1207081/download
The problem, of course, is that in the US we have a First Amendment; our Congress is disfunctional at even passing basic laws to keep the country operating: also Americans don’t love weird speech laws. Some legislation was proposed, but it died. https://www.judiciary.senate.gov/press/rep/releases/graham-cotton-blackburn-introduce-balanced-solution-to-bolster-national-security-end-use-of-warrant-proof-encryption-that-shields-criminal-activity
What’s important to note here is that *Apple’s system did not get rolled out.* It very publicly failed. Apple eventually delayed and then canceled the proposal entirely.
And they even rolled out end-to-end encryption for iCloud. https://www.wired.com/story/apple-photo-scanning-csam-communication-safety-messages/
@matthew_d_green some of the proposed amendments are indeed excruciatingly bad. but the actual current legislation wording is pretty simple... and terrifying: it simply says that the regulator can mandate "content moderation" (i.e scanning) to mitigate CSAM & terrorism. We tried to summarise at https://news.ycombinator.com/item?id=34923537. Even if Apple isn't doing OS-level scanning, this clause sets a massive precedent for other govts to try to follow, even if the US holds out.
@matrix @matthew_d_green Thank you for summarizing the bill in a simple way! Ugh, this is terrible. Private communications are a human right.
