@kopper is the above wrong or misleading anywhere. do they really force you to construct a json-ld by hand before sending. i will tell you that that is a textbook problem in group messaging crypto and if ap really actually forces you to unbatch everything into json-ld to send i will be shocked and appalled
@kopper like signal's other single trick from centralization is that you send one group message with several recipient keys, the server splits that out for you, and you actually get a small surveillance resist buff bc you don't highlight every group member individually per message. you can do this better non-centrally but batching isn't just a perf number it is actually very relevant for traffic surveillance.
