Encryption must never be backdoored. This is something so fundamental to the notion of what encryption is, that there must never be a compromise here. Pulling an encryption feature rather than rendering it worthless is the only noble path, when faced with these options. Removing Signal from the UK app store (when the addled bureaucrats target it next) is the only noble option.

Signal is the least of our worries, Apple are removing encryption from iCloud in the UK. They don’t have the balls to withdraw from the market though.
This is in response to Apple. They're removing encryption from iCloud in the UK, *because* the UK is demanding a backdoor to everyone's encrypted information. They're not roaching out: they're taking a hard line on what encryption is fundamentally, and what cannot happen with it.
