I've emphasized a few times, that examples are made up (for a purpose of explaining different scenarios). I haven't included any actual opinion to make it even more apparent.

You should it read it like this:

_given_ [ A is right and B is wrong ] this and that _may_ happen

with emphasis put on the word "given".

In real world are usually more than two actors and multiple mutually exclusive narratives; authors even when deliberately lying include some truth to make it more believable etc etc, my point of the previous post was that adding a new source with an agenda usually does increase the noise, but not _necessarily_ the signal.
