This is especially apparent in the 'worldview' sorting under the `bias` section, which lists the German FDP to be further right than the CDU (which is nonsense) and also barely registers the FDP as libertarian when they are a free speech, small government, personal responsibility and free market party. They also register "Die Linke" as Libertarian-Left, which could not be further from the truth. "Die Linke" barely has libertarian values at all, being pro state-governed economy, having an ultimate goal of democratic socialism and they're certainly big government. They're also leading a large deposession effort for large landlord companies. I'd honestly put them into "Auth-Left" territory.

So yeah. The bias is a bit nuts and you could reasonably accuse the study/report of misdirection/misinformation and plain fasehoods.
