> If you refer to the theory that AV actually wrote viruses (it's not clear), that's as realistic as saying that police commits crimes so that they can get extra reward from the new tasks.

This analogy is not helping your case at all. It's not unheard of for police to plant evidence for such purposes. It's also been proven that law enforcement has been willfully using technology having high rates of false positives for things like drug testing to bring real charges against otherwise innocent people.
