Comments and Reviews

   
Comment summary: Matrix receives praise for its open-source, decentralized nature, self-hosting capability, and bridging features supporting multiple chat protocols. Users appreciate its security and flexibility, but note drawbacks like sluggish performance and challenging room permissions management. Serious concerns are raised regarding alleged links to Israeli intelligence, potential metadata leaks, and inconsistent community moderation, leading to divided opinions on trust and privacy.

Matrix stands out as a messaging tool since it's secure, private, and distributed. Underrated IMHO.

"Matrix was created inside of an Israeli Intelligence Corporation called Amdocs: https://web.archive.org/web/20201219014215/https://samba.noblogs.org/post/2018/08/27/matrix-org-a-federated-app-funded-by-a-mossad-company/

(...) it also leaks lots of metadata, in many cases not fixed to date. The homeserver can and does store lots of metadata. Even if you run your own instance, it still sends data to the main homeserver."

Want this to be what it says it is. However after a month of using, Matrix through Element, I can say it's not worht anyone's time.

Some of my first chats on there were with people explaining why a lot of members on the chat had moved to other platforms with less controversy. I noticed lots of groups with few members or little activity.

I joined about a dozen or more. However after participating in discussions for a few weeks I found myself in trouble for doing just that.

I posted a message in both the official "Matrix HQ" and in "Element" asking people on their thoughts about Matrix/Element vs a FOSS competitor someone in another chat room had sent a link to a community on. Within under a minute I had a user message me and say "Don't Double Post" and I was banned from more than half a dozen communities, including ones I had joined but never used.

I checked the policy on the threads, nothing against double posting. I tried to message the admins of the main. "Blocked". It even seems like my account is broken now and doesn't run properly. The more I've thought about it, seems like they don't like people talking about other applications. If this were just anyone's community fine whatever, but from the official help and support threads and other related communities. This is incredibly sus. I think the user who told my why half their chat left the platform when I had first joined made to much sense.

Also after doing research the last week on the platform. "Creative Joe's" Israeli Intelligence connection, and data leak stuff all tracks.

Don't use this app if you like security, don't use this app if you're looking for safe communities because it's built by people who don't care about you and will ban you if you bother them even once without warning.

matrix just works, decentralized fediverse, self hosted servers, several clients.

although one thing i hate of matrix is how it manages roles/permissions in a room. if you ever lower your power from 101 (founder) to 100 (admin) by mistake, then that room will forever be founder-less. they dont automatically make someone else founder if you demote yourself or leave the room
