You appear correct that his inside information is not perfectly accurate. You want some of my thoughts?

Either the Swedish Operator is good or he's evil. If he's good, he'll speak what he believes to be true. If he's evil, he will speak what manipulates you into his bidding.

If he's Good, his mistakes are the location of the outbreak (Wuhan vs US) which can be explained a little bit by this:

The other mistake being the number of deaths by the vaccine. Is that because their poison wasn't strong enough, or are we just not being told about the countless millions dying? The virus did emerge at the furthest possible point from a census. Or do those 10 million deaths include every vaccine related heart attack for the next 2 decades? I don't have a guess.

Now, if he's Evil:

The Evil man would know the vaccine works. The evil man will be the one with the deadly virus who wants to make sure people don't protect themselves from it. "Do Not take the antidote!" our enemy pleads.

Could be either. If he's evil, the disinfo is a Russian MO.
