alt Hacker NewsMatrix is controlled by a single company Riot.im/Element.io who decides what the protocol is now. Element.io's income stream is hosting these extremely fat synapse servers for government. It doesn't really care about anything else. The Matrix Foundation has abdicated from it's role as of a couple years back (ref: https://element.io/blog/element-to-adopt-agplv3/ https://matrix.org/blog/2023/11/06/future-of-synapse-dendrit... https://blakes.dev/posts/2023-11-06-element-closing-matrix/). And generally synapse servers RAM and storage requirements grow and grow and grow, with no effective mechanism to trim the DB, until it requires hundreds of GB of ram just to idle and it starts becoming very expensive and infeasible for non-government/corporate pocket books to pay for. Even with just a few users the min ram suggested is 8GB at the very start.
For human people, for small social groups, Matrix in the form of the controlling Synapse server is infeasible over any period longer than a few years. See: https://news.ycombinator.com/item?id=46376201 / https://news.ycombinator.com/item?id=44617309 and the reports there or just ask around. I know Afternet gave up Matrix because of this despite really liking the features too, https://afternet.org/help/matrix
There are other Matrix protocol servers but none that implement the full protocol. Conduwuit was the most full featured but died, now there's https://continuwuity.org/ and a tiny bit of hope.
tldr; the Element Synapse matrix server uses too many resources (and they killed dendrite). We all wanted it to succeed but it was co-opted. Alternatives are not in control of the protocol, few, and of limited lifetime so far.
XMPP and IRC are the better alternatives.

The governance of the Matrix Spec has always been open, as explained on the website (https://matrix.org/foundation/about/) and in the Matrix Spec Change process (https://spec.matrix.org/proposals/).
Meanwhile in the last 2 years the Foundation has evolved a lot, in particular with the election of its Governing Board (https://matrix.org/foundation/governing-board/) representing all stakeholders of its ecosystem, and which has an advisory role to ensure the independence of the Foundation. The Governing Board has also set-up several Committees which are hosts to Working Groups which help run the various activities of the Foundation (https://matrix.org/foundation/working-groups/). You will note in particular the existence of the Governance Committee (https://matrix.org/foundation/governing-board/committees/#go...) and its corresponding Working Group which “exists to determine how The Matrix Foundation should be structured. It determines why the Foundation is structured the way it is, or look for alternatives when the Foundation has visible flaws.”.
In terms of the Foundation developing its own software: it has been a deliberate choice to not have any development (beyond moderation tools) within the Foundation. The reasons for it include the fact that the Foundation is already running at loss and can’t afford to pay a team of developers big enough to develop and maintain all the bricks of a Matrix stack. If the Foundation decided to develop everything itself it would need to set up revenue lines which would probably compete with the various vendors in the Matrix ecosystem, so the Foundation would rather support an active ecosystem than cannibalise it. That said, it may change in the future if that is the best choice for the project; or a Matrix vendor may choose to donate the code of their stack, like Element was donating Synapse until freeriders destroyed its business and forced them to fire half their employees to stay alive.
In terms of Synapse’s efficiency, it has improved lately despite losing some of the team, and thanks to having stopped dispersing the resources across two server implementations in parallel, and focused on one. As you say Continuwuity is an alternative implementation to look at if you are unhappy with Synapse.

That they don't care is unfair, they just do what makes them survive.

I know companies that have done so. The resources requriments are bit higher then some alternatives but its really not has crazy as you make out to be.
There’s hundreds or thousands of people out there hosting Synapse for small groups and use cases. Ressource requirements for a couple of dozen or hundreds of people are pretty tame (mostly storage that grows fast). You can easily host Synapse on cheap VPS products for less than 5€/month. I’ve been doing this for multiple organizations and many years.
