I am against emi ent domain but at least it is justified by the fact that there are no alternatives. A road between two points must pass through some land, but if a domain name for your website isn't available don't be a bully and buy another one. Also you have to compensate with eminent domain, you can't just take. Not in decent societies anyway.
What we have here is maximum statism. A bunch of french bureaucrats had some stupid idea on how to spend stolen taxpayers money to "improve" society, and they used their position to steal a domain name from a guy who was minding his own business.
In this case bureaucrats should be condemned as if they were thief.
