non-tech people are scared by the term "hack", so "jailbreak" is a useful term for communicating with the public/non-experts when it comes to the intent of the hack. And useful terms tend to stick around even if they're not used with the original intentScam site.
They're notoriously known for plaigarising Wololo.net's articles as well.
I would remove the link if I were you. You would just be giving that site more attention, which in turn, bumps them higher up the search engine results...
As mentioned, stick to the official http://wololo.net site, which has its own (real!) news and updates about (real!) PS4 software hacks and "jailbreaks" (do people seriously say jailbreak still? Thought that was just for iPhones...)
