"There's a historical precedence for people drinking water and dying because of it, so I'm not going to drink water anymore."
The reasons you here about them is because they are so exceptional. People got banned from forums for being irreverent dicks before and no one batted an eye. Now because they got legitimized by gullible people, everyone screams about their lack of freedom on private platforms.
you're poorly versed in internet culture and history. many internet subcultures have axiomatically rejected moderation because, surprise, giving power to anonymous and unaccountable peers frequently results in abuses. you're confusing your own lack of concern and love of arbitrary authority with the opinions of others.
I've seen this dynamic play out first on tiny communities like MUDs where you'd have, at most, a thousand people. Later the pattern repeated over and over at larger and larger scales, where more recently you see entire platforms like Reddit suffering from the same issues. Each order of magnitude increase in user base makes the threats grow far more exponentially in scale.
Soon the whole internet will become rotten, culturally speaking.
