The above post is basically just this article, I think it's important so I'm linking directly. Plus it will preview the image.
I'm also going to completely steal this snippet from the post, again because I think it's important.
Why Signal is Better for Furries
First, Signal has sticker packs now. If you want to use mine, here you go.
For years, the main draw for furries to Telegram over Signal was sticker packs. This is a solved problem.
Second, you can setup a username and keep your phone number private. You don’t need to give your phone number to strangers anymore!
Finally, it’s trivial for Americans to setup a second Signal account using Twilio or Google Voice, so you can compartmentalize your furry posting from the phone number your coworkers or family is likely to know.
The last two considerations were really what stopped furries (or queer people in general, really) from using Signal.
Back to my words now.
I know there's other factors involved, but I do not see the current technical nor social issues of Telegram being resolved within the platform. There are options, they should be explored and used. Web platforms are thankfully not like real life housing: you can just leave.
