What?

I don’t think you know what centralization/decentralization means.

On matrix, you scan spin up a server/instance and communicate with any other matrix server/instance. On Fluxer, if you self-host, and your friend also self-hosts, your instance/server cannot communicate with your friend’s instance/server. You would have to create an account on your friend’s instance/server and vice-versa. You would also, probably, have to be running two clients in order to chat in both servers/instances.

This should serve as motivation to move away from any and all corporations. Do not lose your community. Find a proper free-libre-open-source alternative and move the community there. Communities are important. Corporations are not.

Slightly Off-Topic:

I never liked Discord. First and foremost, nowadays, I cannot log into it when I am using a VPN. And back when I could, it always felt so laggy and clunky.

I think todays society is not used to performant software. Everyone just buys a new computer/smartphone every year or every 2 years or so, so they probably have compute power to run whatsoever. I run old shit. 13 year old desktops or so, with no dedicated graphics card, old smartphones, etc. I need software to be performant.
