Continuing to do business with Kiwifarms is an acknowledgement that individuals are responsible for their own actions, and any illegal activity such as swatting is the fault of the individual.
Are Mark Zuckerberg and Meta responsible when people livestream murders or plan terrorist attacks using Facebook? Obviously no.
Now I will acknowledge that there's some dispute over Kiwifarm's actual role in any illegal activity here. Did they encourage or organize criminal activity? As somebody who hasn't followed this drama from the beginning and who doesn't know what actually happened on Kiwifarms, I'd be a bit interested to try and read the source to try and somewhat figure out the truth of what happened for myself free of bias about who did what to who. Unfortunately, after shutting the site down, it's now impossible to get an objective answer after the fact and piece together the truth about this drama for myself. And trusting corporate claims or biased actors on any side of this story is just about impossible in today's hyper-politicized world.
