By 2020 Greenwald was basically persona-non-grata for not pulling either US party lines and his strong support for people like Snowden. Despite his great work in Brazil on human rights and anti-corruption which is something that goes beyond partisan politics and should be lauded.
The problem is people trying to put him (or everybody) into convenient boxes - representing singular view points - without shades of grey, like the 24 hour news talking head guests pushing sound bites.
The type of pressure on any person who dares to enter political news for a living. Which to me seems like a never ending gauntlet.
If tomorrow Sanders starts spouting antivaxx stuff, and half the internet starts attacking him, you wouldn't go and say "there's a misinformation campaign astroturfing against Sanders".
