Signal has long said it'd "rather shut down or leave a market" than add a backdoor or weaken its encryption.
Apple also had this option when it was ordered by the UK government to build an iCloud backdoor. Apple could have said — without violating secrecy laws — why it was leaving the UK, rather than weaken the security of all of its UK customers.
Instead, Apple capitulated to the demand to keep operating, and prioritized its profits over its customers' security.
@zackwhittaker The Signal comparison doesn't really make sense because Signal has no presence in UK, does not have customers (much less in UK), and will continue to serve people in the UK as a hostile rogue state that infringes basic privacy rights if needed, just like they do in other such states.
Apple on the other hand, as a business, has not set things up to protect the people in hostile jurisdictions who rely on their products in the event that they withdraw. This of course is on them, and on capitalism, but it doesn't admit the same path forward.
