It isn't a conclusion, it is a comparison.

Signal is not the best mainstream option, because it was never really adopted by mainstream despite being promoted by western governments and left-wing groups, lest not forget it appears plenty even on holywood movies.

Still, Telegram has defacto been the best mainstream option without any of that. It is the non-acceptable option by western governments and yet used so often by the "mainstream" that they had to arrest the founder.

SimpleX is similar garbage to both signal and telegram. There is ZERO benefit in repeating the same mistakes of the past. SimpleX is a small russian company, that now received western funding. There is only ONE client implementation and ONE server provided by default by the same company for "free". In other words, they can easily disable any encryption for the "special" people as done for other options. You can't really verify and your messages aren't decrypted at their servers because you can't even guarantee they haven't stolen your private keys (tip, they are stored locally).

NOSTR is the future.

Hundreds of relays across the globe run by volunteers, dozen and dozens of client implementations and verifiable battle-proven cryptography that govs have a bad day trying to decrypt.

That is the reason why I'm here.
