That's not really true for quite some time now. Both client and the free server depend on a separate submodule that has no LICENSE file whatsoever. Because of that RustDesk is stuck in a limbo somewhere between open source, source-available and closed source. Also, the whole management of the project seems questionable. Also for some features a dll blob which is not open source is required with no source disclosed at all.
