The right-wingers that got banned presumably broke one of Twitter's rules - maybe they said "I wish someone would shoot (insert politician they don't like here)". Even if you take "pre-Musk Twitter had a left wing bias" as granted, that doesn't mean the right-wingers were wrongfully banned.
>But banning antifa-accounts, that is accounts held by people taking part in month long riots and looting and political real-world violence… that is bad?
The only way to boil this down to a politically neutral rule is if we banned every right-winger who was at the Capitol on January 6, 2021 alongside everyone who went to a BLM rally that turned violent in 2020. And as far as I can tell neither behavior alone was a violation of Twitter rules as they stood at the time. The rule was no inciting violence on-platform, not no being involved in violence whatsoever.
As far as I can tell, pre-Musk Twitter had two biases:
- Their moderation team was understaffed and overworked because Twitter was too big of a target to effectively moderate. Twitter moderation would overprosecute easy-to-detect cases (i.e. LMG staff getting banned for months because of them sarcastically saying "I'll kill you") and underprosecute difficult ones (i.e. everyone harassing Twitter's villain-of-the-day).
- As a direct consequence of this, right-wingers were more likely to be banned. This is because their rhetoric is inherently more violent[0] in ways that were easier to detect.
Musk has basically decided to cut the moderation team in half and unban all the right-wingers in the name of "balance". All this does is say "we are now letting right-wingers break all the rules, but left-wingers must be on their best behavior, if we let them stay on the platform at all".
