Exactly. Articles like this are fine and all, but they're generally preaching to the choir; the audience they really need to reach is indifferent to the arguments, and like it or not, calling for someone to be cancelled is also an exercise of their free speech rights.
Social networks don't want to change anything, because culture wars drive engagement (even if they slowly make the platforms uninhabitable).
I don't know what's to be done except to move away from social networks into smaller communities (Slack groups, etc.) that have their own norms of discourse.
Is there any public evidence that outrage-driven engagement is profitable? It's a statement that is frequently repeated, but I haven't seen any evidence for it.
