Exactly.
The problem is that it is very simple to abuse these laws, because, in the haste to “save” us from terrorism, the lawmakers have put very few checks and balances in them.
France has even more draconian ones on the books, you can get up to several years in prison for “apology of terrorism” - simply saying in public (on Twitter, FB, …) that you agree with what e.g. IS is doing or that “it served them well” (e.g. with regards to victims of an attack) is enough for the prosecutors to bring charges. Several even high profile people landed in trouble because of this recently, including a mainstream journalist.
Another thing that could get you charged with being part or helping “an association of criminals or a terrorist enterprise” is simply searching for and visiting djihadist websites. Also several cases of this were prosecuted recently.
The important part is not what you get charged with but what the courts will do with it. The French courts are very independent and tend to frown on inflated BS charges. On the other hand, if that person has some connections to IS (knew someone who knew someone who left for Syria, chatted with someone over Telegram, etc.), links to extremists or is a known “troublemaker” (the controversial “comedian” Dieudonné comes to mind …), then they will be happy to use even these laws to throw the book at them.
