A non-trivial reason I bought a fairly closed device (macbook) was that Tim Cook, at least publicly, told the FBI to get bent when asked to create a backdoor. Exactly what I want to see, a fight in court.
I would hope to see Apple pull out of the UK market over this, and certainly to stop selling Apple devices to the UK government and to remove the UK government entities from Apple services.
They dont really need to pull out, instead on every single piece of marketing material where they talk about anything remotely close to things affected by this they mention that unfortunately they cant give it to UK users due to the governments desire to erode privacy protection, and really hammer home how bad it is.
This happened 18 months ago, you can stop hoping.
I love this. Apple aren't going to pull out of a market. They aren't pulling out of China for example.
