Springer is the publisher of Bild and Welt (among others) , two major German papers (Bild is the biggest in Germany).
Especially Bild is known for its right wing populist tendencies
Some more recent examples (all in German for obvious reasons)
- their own former (vice) editor in chief of accused them of spreading Afd (Far right/partially facist party) naratives: https://www.tagesspiegel.de/gesellschaft/medien/ex-bams-chef-rechnet-mit-bild-zeitung-ab-3991837.html
- Recently Bild has been credibly accused of pushing a narrative against a clean-heating law on behave of Springers owner, a fossil fuel company, https://www.lobbycontrol.de/lobbyismus-und-klima/springer-konzern-nutzte-hauptaktionaer-kkr-den-medienkonzern-fuer-politische-einflussnahme-118529/

- they have been actively supporting for the current CDU-front runner in bevoming the CDUs candidate over more moderate options (Merz is on the right of the CDU, the big conservative party in Germany: https://bildblog.de/104902/bild-am-rande-des-merzinfarkts/
- during Covid they pushed against lockdowns and 'the politicians responsible': https://www1.wdr.de/daserste/monitor/sendungen/bild-skandal-macher-100.html
- intended (and did) directly push the Fdp (libertarian party) to avoid the "red-green disaster" (i.e. a coalition of Spd (center-left) and greens (also center-left)) during the last election: https://www.n-tv.de/politik/Kann-man-noch-mehr-fuer-die-FDP-tun--article24049439.html
- played a major part in agitations against refugees during the so called 'migrant-crisis': https://forumwk.de/wp-content/uploads/2021/07/Medienanalyse_Flucht_Migration-1.pdf
- this was their front page just now (we have a national election tomorrow):
There is honestly a lot more I could put here. In Germany the Bild is well known as a populist right wing paper. It is not exactly new either. A famous quote from the Punk-Rock song 'Lasse Redn' (2008) when describing the papers content is "Angst Hass Titten und der Wetterbericht" (fear, hate, tits and the weather). The common hastag when talking about them in left-leaning circles is #haltdiefresseBild (shut up Bild). There even is a Browser extension dedicated to block all Springer owned or published products.
While some of its other papers seem more nuanced at fist glance, they often push similar narratives packaged for their respective audiences.
Gutes Beispiel!
