IMHO it's CSAM that is at the root of all of it. I don't think everyone is fundamentally animated about "spam", monetary uses, etc... That's all wonky stuff and if it were just that then the discussion wouldn't have spilled over into this flamewar. CSAM raises the temperature to thermonuclear.

And it reflects the broader problem of how to police the "commons" of decentralized internet systems, where I don't really think there are easy answers.
