This may be kind of nitpicky, but I feel like the wordage for the Instant Messenger section is kind of clumsy. Both Signal and Briar are directly stated to have perfect forward secrecy, which makes sense, but SimpleX has it as well though it isn’t mentioned other than in the criteria. Signal is highlighted for post-compromise secrecy, though SimpleX also has that and that isn’t mentioned. SimpleX is highlighted for its double-ratchet encryption, but Signal has that too and that isn’t mentioned.
Maybe this can be solved by having a comparison table for messengers, to show overlapping and differing features. Then, the descriptions for each messenger could be simplified a little bit.
