It was whinged about incessantly in the popular press though (even on HN) as being anti-entrepreneurial, anti-business and something that would lead to an exodus of rich people from Paris (as if lower property prices were a bad thing).

I think the thought mattered more than the actual tax. You could sense that the ultra-wealthy all around the world hated it. Made them feel persecuted, perhaps, despite it being ultimately pretty toothless.
