"Libre file transfer client for macOS and Windows. Command line interface (CLI) for Linux, macOS and Windows." means that technically the version for free systems does not have as many features as the versions for proprietary. But given the type of tool it is, you'd generally just want the command line version anyways. Need to determine what the boundaries are on the requirement for parity - not usually an issue we delve into too much.
