Copyleft licenses are restrictive as obligations are restrictions. "You must provide a source code to your users" is equivalent to "You cannot use this software if your source code is not available to your users".
Freedom is a finite resource in which copyleft licenses take from the developer to give to users. (which ends up at the same point as the article but I prefer wording it this way.)
