Whether or not spreading misinformation on the internet is justification for removing someone might be up for debate, but let's not pretend it was just because they disagreed with the "big tech" company that is wordpress.com
Honestly, as somebody on the left, I do feel like there are certain topics that people get unusually emotional about (e.g. terrorism, airplanes, covid) and tend make choices that aren't proportional to the measured risk, relative to say smoking.
Usually the rule is that when it only affects the believer, it's ok. There are, however, sensible arguments against it based on the damage those beliefs cause to others, in special children of Jehovah's witnesses as individuals and the collective risk children deliberately not vaccinated going to schools and spreading disease to kids who can't be vaccinated (because of age or allergies or any other medical reason).
The idea of "dangerous misinformation" is an anti-liberal, anti-Enlightenment notion. Information is not dangerous, information is neutral. It's either right, in which case it's not misinformation. Or it's wrong, in which case it's not dangerous, because it can be refuted.
The most dangerous thing is to suppress the free marketplace of ideas.
What to do about dangerous misinformation is of course another question entirely, but the idea that there’s no such thing ignores important challenges.
I miss the days where "common sense" or "simple logic" wasn't labeled as some ideological "wrongthink." We _literally_ can't do business with each other being locked down because people in the US are being stupid about managing COVID-19. Don't blame "business culture."
