I worked in the media analysis field before and know very well how to handle my sources of information. For me the term MSM does not make sense: everyone has affiliations and agenda, whether it is NYT, RT or some random guy in Telegram or Discord. Working with NYT or RT or Bild is easier, because you know how their distortion bubble looks and where extra fact checking is necessary. Publications in anonymous social media accounts are worse - there must be zero trust by default.
