For example, for Element Web, if one tells the browser to force system-wide fonts and sizes or when setting Element Web's font size to 20pt, the default style turns into a headache waiting to happen (see attached screenshot), so one still has to learn how to program in their browsers' native extension language, how to fiddle with CSS, and figure out how to bring the style inspector and build the CSS selectors for the right elements they want to tweak in order to have a subnormal-monocular-sight-friendly Element Web Matrix client. For other clients, like Revolt and Quaternium, the configurations for that are yet to be known. Also, contrary to XMPP which has at least two fully-functional free/libre software clients, for Matrix there is only Element non-Web has full functionalities of the protocol, and that is not even free/libre, because at least in Element Web you can't use the client's own search feature for conversation or media histories in encrypted conversations. Furthermore, the Matrix protocol itself is not internationally standardized (but rather auto/self-standardized, meaning that they can change that at any time), and some clients allow for link forgery since the Matrix protocol didn't dictate what would be the message format and clients decided to implement Markdown formatting, which is dangerous in the context of instant communications. Discarding audio/video conferencing support, Matrix servers take up more resources () than XMPP with all suites/parts of XEP-0443 (, again discarding audio/video conferencing). Also just like Matrix, XMPP servers and clients that support XEP-0313 for both individual chats and group ones (MUC or MIX, although MUC is more popular) do provide ways for the user to catch room history (messages received by the room while that person was offline) While FSDG-fit distros have plenty of XMPP libraries, clients and servers, Matrix-related ones are lacking there, so one often has to thrust the single-language package manager installation instructions given by the library/client/server that you want to install, unless there is a FSDG-centric review of each of those apk/pip/npm/gems/docker/flatpak/rocks/cargo/snap packages/dependencies. To balance the sides, both Matrix and XMPP *do not* provide default bots/puppets/bridges/transports to other communication protocols. I was once lured by a person to investigate that since they claimed that Matrix had bridges for IRC, XMPP, and others *by default*. But it turns out that this is not the case, and you have to either trust the centralized Matrix.org or risk installing one yourself through the methods in the previous paragraph. Finally, there is also the privacy and centralization issues regarding Matrix, since it is mostly centered on Matrix.org (while there are instances that do provide account creation, only Matrix.org has bots/bridges/puppets which are clearly documented and exposed/discoverable). # References : https://disroot.org/en/blog/matrix-closure . : https://xmpp.org/extensions/xep-0443.html . : https://xmpp.org/extensions/xep-0313.html .
It seems like the FSF already has evaluated the possibility to
use XMPP and Matrix, they declined both of them.
At the same time, we could not commit to moving fully over to XMPP, which would impose certain technical limitations on both users and FSF staff, and which does not offer many compelling advantages over IRC. We've also definitely heard from many of our members showing renewed interest in the XMPP server the FSF provides as an associate membership benefit, and we are looking at the possibility of devoting more resources to it. To reiterate, though IRC remains a key venue for communication in and around GNU and FSF, we are keeping an open mind and eye towards other existing or new communication protocols and software, including Matrix and XMPP, that enable users to communicate in freedom."
