It's probably worth pointing out that many of the most important anti-surveillance tools like Tor, Signal etc survive on minuscule budgets, most of which are from US based institutional or NGO grants (open disclosure: so is Umbrella App which we make). If the UK or others really wanted to hamper them, going after the funding for maintenance, not the tool itself would probably be more destructive in the long run unfortunately. Yes open source is great etc and might survive but development would drop dramatically.
