Yeah. For me, Signal’s security benefits are counteracted by various other usability issues. Such as not being feature-complete on desktop and not even allowing registration there without workarounds - given that phones are very privacy-invasive by default and far from all can have a privacy-respecting OS installed (while Linux works on pretty much any random computer). Or even on mobile - pushing the user towards Google download with dark patterns, not being on F-Droid, or (at least in my experience) the official app not working at all on my Graphene device (Molly worked perfectly though). Also, from what I’ve seen, even if you don’t mind losing connectivity with other users and would only converse with people on your server anyway (like how I do with my family on XMPP), selfhosting Signal is really hard compared to XMPP, Simplex or even Matrix, even requiring modifying the client app.
Not me, but my mother has beef with air conditioners. When I was little, I got sick (to the point of losing consciousness) due to a dirty AC in a hotel, so now she (maybe rightfully) assumes that a random given AC in a public place is filthy. We don’t have one at home either - mostly because in this climate we’d only need it for a short time each year, but also because mom thinks it’d be easy to not take care of it properly and let enough filth accumulate.
