Wait, how is that different from Matrix? My Matrix server only syncs with rooms that I've joined, which is the people I'm chatting with. It's not like a Matrix server just starts syncing random rooms you're not in. I assume that an XMPP server has to accept events on your behalf when you're offline, right?

It also makes requests to the keyserver at matrix.org. Integrations make requests to vector.im. Also there are analytics gathered (which are disabled by default) that get suggested to activate in the server documentation e.g. some default config snippet. They all can be disabled/are disabled by default, but the fact that such centralized services exist in a "decentralized" protocol and get suggested to you is outrageous.

And the network traffic while idle is abnormal. Also if you disable the default keyserver, your server makes even more requests than before.

Maybe i'm exaggarating or misunderstanding something but with prosody i still had the feeling that i'm under control, that i know what happens and what connects to where and it didn't consume as much ram/cpu.
