Twitter's position in those interviews is consistent and does not show bias.
I've watched that interview and others. The position of Twitter has been consistent and actually fits the facts of being reasonably non-biased. It just seems that way because the pattern recognition of harassment behavior, is flagging people in ways that seem to bias some arguments. They are actually just trying to promote productive discussions and discourage harassment as a means to win arguments.
No one was banned because tweeted an 'N' at someone. They were banned because they used multiple twitter accounts, participating in harassing people by tweeting one letter of N-word at a time to people.
Similar with the gender issue or dead naming. It was the behavior of attacking an individual, instead of an idea, that was flagging the bans. So it is the behavior, that would have gotten you banned with either left or right wing positions, that is getting the account penalties.
Now to the anti-capitalist right wing whiners like Tim Pool, Twitter is under no obligation to destroy its shareholder value by keeping toxic people on its platform. It is not a public service and is not getting public money. (Just because a bible publishing company won't publish your gay porn book does not mean your free speech has been violated.) You are free create your own platform or make the government provide one. Saying that no one will use the new platform only proves that Twitter is correct in assessing that some people weaponize, what is technically free speech, to harass others out of the conversations.
