@ambiguous_yelp @sammi @joelanman To be clear, I pestered Meredith over and over about this when the official word was that they would withdraw from UK.
Understandably Signal didn't want to give away their hand early, but ultimately she clarified that this would mean treating UK like other hostile states requiring circumvention of law & possible circumvention of network blocks via proxy infrastructure, and that they were committed to protecting UK users.
