Do you consider is censorship if a huge Internet/media company removes illegal content like child pornography, explicit calls to "imminent lawless action," phishing/fraud attempts, explicit misinformation (like false claims that an election date has been moved), or content that goes against their own community guidelines (pornography, violence, etc.)? Do you consider those things censorship or opposition to free speech?
You're mixing up two different things: sites removing illegal content because they're mandated to do so, and sites removing legal content because they choose to do so.
