I read the article, and it’s hard to see how this would have worldwide effects. If anything, the companies with customers in the UK will: disable E2EE for chats with UK parties (likely warning the parties); leave the UK market rather than weaken their brand; or create a secondary product just for the UK. Consumers will continue to find workarounds provided the phones and computers are not fully controlled by the government.

The fact that the government would have to force client side scanning software onto phones and computers is probably the death knell of the UK tech industry. Either that, or so many exceptions will need to be added that the legislation would be ineffective. Can you imagine a Linux hacker recompiling their own kernel and then getting thrown in jail because they didn’t enable the government scanning module?

The reason it will impact security worldwide is that the UK is part of the “14 eyes” alliance, an alliance used to spy on citizens. Any encrypted data going to or through the UK will need to have this backdoor, exposing all encrypted traffic to this vulnerability while also sharing that data with foreign governments. Edward Snowden exposed that the US government was paying the UK government to spy on US citizens for the data. This is what will happen in the UK, but for people around the globe.
