There is only one substantive reason I am aware of: power.
I'm sure you can find more substantive arguments if you try.
Wanting to suppress discourse isn't a substantive reason. Saying that's the "substantive reason" that people want more content moderation is just a fancy way of calling those people bad people.

Don't like someone's politics, or are they too effective at counter-narrative? Cancel them. Destroy. That's the message. Maybe you are not such a wrecker personally, but the mob you may belong to always is.
Nobody escapes the mob, and they always end up eating their own. Don't step outta line, comrade!
