The difference is that they aren't using this to make online conversations more polite or something (not that I agree with your point that removing anonymity somehow is better for free speech, at all). This isn't some sort of initiative to promote self policing. It's to get information that will allow authorities to arrest people and put them in jail. That automatically makes the entire argument that it could be beneficial for free speech and promote more "real life" like interactions online irrelevant, because that's not the point of this law.
