in the past, the argument many experts have used against putting in the effort to actually correct people's misconceptions about what a computer virus is and what it does and how it's different from other forms of malware have centered on the idea that it doesn't really matter to a victim what kind of malware they have. when they have malware on their computer, all they care about is getting rid of it. i can understand this school of thought, even though i've never agreed with it. however, the world has changed.
this is a post stuxnet world and defenders/victims aren't the only ones we need to consider anymore. we now have people barking orders to create digital weapons, and the details of those orders matter. if they say make me a virus then someone will make them a virus even if they didn't understand what they were asking for - and there's evidence to suggest they don't.
stuxnet is generally believed to have been a targeted, covert operation, but it used a noisy, untargetable* type of malware - a computer virus (or more specifically a worm). there were and are better ways to achieve the ends we believe the creators of stuxnet were after, so one can only assume that high level decisions were made in ignorance of the differences between malware types and the consequences those differences would have on that type of operation.
the question, then, of whether to put in the effort to educate people about the proper use of the term virus can no longer be answered by looking exclusively at the victims who want their computers to be clean. it is now also necessary to consider aggressors who want to use malware as a weapon to serve national interests. as misguided as such behaviour is, we have to accept that it's happened and will continue to happen, and actually knowing the differences between malware types may mean the difference between a surgically precise operation, or one with a lot of collateral damage.
this isn't to say that i think we should start helping aggressors create and/or launch their digital weapons. i still don't believe in helping the bad guys, and even if i believed such nationalistic aggressors weren't bad guys (which i don't), i don't believe there's any way to help them without also helping those who are much more unambiguously bad. what i am saying, however, is that this particular form of ignorance that experts have been too lazy to address can cause real harm and ignoring it means ignoring the opportunity to reduce the unintended harm such people will cause.
(*many believe stuxnet was highly targeted, but there's a distinction to be made. while it's destructive payload was highly targeted to a very specific environment, it's self-replication was not - it spread far beyond it's intended target)
