The bridges do not run inside the client, they either run on your own self-hosted server or our cloud.

I already have a Matrix server with the bridges I need running. Can I still use your desktop client? It looks sick!

> Then aren't you required to AGPLv3 the desktop client, too?

Only if the desktop client is legally a derivative work of the bridges.

The "network connection" provision of AGPL doesn't require you to open source anything you use to talk to it, just modifications of it. To make it clearer:

Client <--> Server. The server is AGPL licenced.

I can write a client to talk to the server and I don't have any licence restrictions. For example - if I write a web client to talk to an AGPL web server, I don't have to open source the client.

If I modify the AGPL server, and then put that modified server on the internet then the AGPL terms require me to make available the modified source code.
