UK aims to expand surveillance powers with tech bill, raising encryption and privacy concerns
• Britain already has some of Europe's toughest surveillance laws, but now aims to expand powers further with new legislation
• Tech companies and privacy advocates argue the changes could undermine encryption and user privacy
• The bill would let the government issue notices to prevent tech companies from making updates that could impede data-sharing
• Critics worry the bill creates a new, loosely-defined category of data with "low or no" privacy expectations that could be widely exploited
• Rapid pace of the bill through parliament raises concerns about inadequate scrutiny of far-reaching implications
