The fact that you think you can just handwave away legal obligations like this with common sense is certainly telling. It says you don't know what you're talking about. You could reasonably assert that the government's ban of Kaspersky's software is motivated by FUD. However the ban itself is very real, violating the ban can get you into a world of trouble, so warning people to stay out of trouble for violating that ban is not FUD.
Explained by analogy: Them: "Smoking marijuana can get you into trouble with the government." You: "That's just FUD, it's a harmless plant from my garden, it's not going to hurt me."
