It's not about that but rather the way authorities worded it. They are the government so they have to be extra careful how they present their message because people, most probably, will take their message at face value. In this case, accessing dark web is a potential sign one is a terrorist or has connection to such activities.
It's the same in any government, even more so to the "top ones" because other countries are using them as a "model" or "pattern" for their own use or version. (Although of course, it's not your country's problem.)
From where I live, we're already battling this same mindset that "if you have nothing to hide, you don't need [1] encryption; [2] online privacy; [3] dark web; [4] anonymity. And in our neigbouring countries, it's much worse. We're not even "members" of the "Fourteen Eyes".
