By Arch, do you use SteamOS on your gaming rig? And if not, what would be the determining factor?

It's a valid point that it could potentially create some confusion when a user assumes that everything in Signal is secure. Unencrypted SMS threads could contain an open padlock icon and even an ominous red window border, but someone inevitably will not understand the difference.

However, my frustration has been how both convenience and security is reduced by removing SMS from Signal.

Many people will continue to use SMS for a variety of reasons, necessitating the use of an additional app. So now we have people continuing to communicate over this insecure protocol, but with the additional target vector of potential vulnerabilities in the supplemental app.

Imagine a world where we can adopt a scalable, secure, open communication protocol where users can use whatever app they want. Imagine humanity moving past the diaspora of special-snowflake chat apps and on to better things.

While not a physical radio, a Linux phone such as the Librem 5 in conjunction with an RTL-SDR dongle and external antenna may be a good candidate for a mobile software-defined radio (SDR) transceiver.

SDR frameworks such as GNUradio or REDHAWK are well-established by this point. Newer versions of REDHAWK are designed to run on CentOS/Rocky Linux, however, and they don't (AFAIK) come with a mobile-friendly UI.

I do know that there are some web-based SDR tools in the wild. I'm not very familiar with them, their system requirements/capabilities/limitations, but they could be worth a look to jump-start a Progressive Web App for mobile devices.
