Out of curiosity, what made you choose Simplex over Matrix?

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Matrix leaks tons of metadata, and its encryption lacks perfect forward secrecy. Additionally, it requires an email to sign up, and there are accounts with unique identifiers.
Simplex does not have any accounts or identifiers, everything is stored entirely locally. Additionally, it is based on the double ratchet Signal protocol, with improvements made for post-quantum encryption. It does not require anything to sign up, as there are no accounts. Metadata is not leaked as it is with Matrix, as everything is encrypted or obscured. Messages are padded to 16KB, the sender/receiver is not attached to the message, and there are fake messages being sent to obscure the identity and frequency of contact of those you are talking to even under monitoring of your network. Additionally, for anonymity, SimpleX is allowing for repudiation so that you cannot prove that a specific person sent specific messages, allowing doubt if messages were to be use in a court case, for instance. It is the trend (especially from a security perspective) to implement nonrepudiation, but the SimpleX team decided to remove it to protect users (after years of it being present in SimpleX chat). This is a protection intended for journalists, but it extends to many other cases as well.
Matrix is a nice toy, but SimpleX chat is built for anonymity above all else, and it does that job far better than Matrix ever has or will.
Imo, tbf, Matrix is really more of a replacement for Discord than a direct competitor to something like Signal.
What about XMPP or IRC?
IRC is plaintext communication.
I understand that perfectly, that's precisely why I also listed XMPP. Also, IRC suits the need many people till this day.

What about Matrix?
Not anonymous
Not good initial experience: starts with the colonial UK flag which is not a symbol for languages, site doesn’t quite work without JS so no menu access (popover works without JS), puts proprietary services Microsoft GitHub & Reddit in priority position, using VC funding leads to hesitation, no mention in the FAQs or otherwise how to contribute to the code (not for general users sure, but missing entirely).
I appreciate the effort but yes I do think it has issues
