Ethics aside, piracy is illegal, and most service providers include a clause that you can’t do illegal shit with their service. Even utilities providers aren’t immune to “we live in a society with, like, laws and stuff”. Taking them out of private companies’ hands won’t do anything about that.

And kiwifarms aren’t doing piracy, harming (maybe) the profit margin of some megacorp. They’re enabling and encouraging the harm of other vulnerable people, up to their deaths. If your electricty provider has an acceptable use policy that contains “don’t use the electricity we give you to hunt and kill your enemies” and you Do That, again and again, they’re within their rights (and arguably, ethically obligated) to stop you electrocuting people with the electricty they distribute.

This isn’t “Hurricane Electric haet kiwifarms”; this is KF abusing the service HE provides to the detriment of both society at large and other members of the Internet ecosystem.
