Stallman is basically saying that it's unethical to outsource a software function that it's possible to run on-premises, which is just... a losing argument. Any given user can decide whether the (almost purely abstract) "freedom" of running free software one's own server outweighs the convenience of, say, not having to administer a mail server. I'm not sure what free software buys you versus hosted software with good data export features.
