The problem with politics is that it's very subjective and how the topic is approach matters greatly. There is no ability to 'fact check' the majority of politics. What fact checkers really are is just censors. This article is concerned about first amendment because they are calling for censorship.
Now back to the article, how's the approach? The article also very clearly is written in 1 direction. Covid conspiracies like lab leak, climate change of florida being under water right now, and election fraud where Republicans have submitted 425 election bills across 49 states because they see the election as fraudulent. Are those misinformation or just politically inconvenient truths?
Clear political skew on the positions is the approach here. I'm not in the USA, not American but when you label your political opponent's speech as lies/misinformation. Bad things happen and Trump is the tip of the iceberg of bad things coming because of this activity.
