Signal fills an incredibly important spot in a spectrum of privacy and usability where it’s extremely usable without sacrificing very much privacy. Sure, to the most concerned privacy enthusits it’s not the best, but it’s a hell of a lot easier to convince friends and family to use Signal than something like Matrix.
One of my biggest gripes about the fediverse (and honestly any online community) is people making increasingly niche places to discuss things before there is a need to split things due to size. I’d post that to something like a general hobbies group. I’d also say mods need to be less strict about what is and isn’t on-topic while there isn’t much traffic in their communities.
