Sounds a bit like what Google / Alphabet / Jigsaw are already doing with Outline, but I still think there’s major opportunity there for a transparent and decentralized one-click service. Especially when you add in #4.
For some reason, Outline is still mega-targeted at journalists and activists when it could be so much more — it’s been an absolute joy to use so far, and being powered by Shadowsocks certainly doesn’t hurt.
