The generally accepted definition of 'liar' is not someone who says something that is wrong, but rather, someone who knowingly says something is wrong.
Note that only the third definition is the purely factual
one. When you are using the word 'liar', you are typically implying the first two. (People differ as to whether spreading a lie makes you a liar).
Now typically in science, you only get accused of lying if you intentionally misrepresent your data. This is _not_ what the linked to article says is happening.
For those interested, here's a somewhat more digested summary of the paper (with a few caveats mentioned):
