I think if you interact with non-tech-users, Signal is the go-to; Matrix has way too many thorns for normal users to put up with in comparison to the alternatives.

Also the whole "furries make the internets go" is not really that true. There are certainly many of us in tech fields but going to meets/cons the average furry is not working in technology. The whole "suspiciously wealthy furry" thing just arose from the divide between tech worker and retail worker within the community. Gotta remember that most furries are like 16-25. Many tend to drop out or leave the community over 30-40 or so.
