Maybe, this event may become the precedent for all future hosting providers of unpopular opinions and where denial of service attacks become used against these hosting providers. Losing protection from anti-ddos service(s) becomes a process to eliminate the unpopular opinions being expressed.
I think this is dangerous recourse and even if there are competitor services like cloudfare. There are limits in services available and state actors can understand this problem. Then make it impossible for unpopular opinions to be expressed by either orchestrating what's needed to get the anti-ddos services to resent their customers or by other means.
Me personally, I'm alright with 8chan being deleted from the internet but I don't think that will even solve the problem. People with poor quality of life will continue being radicalized and do these acts of revenge in their eyes against a system that made them live in pain (somehow unjust to their views). I think we just need to improve quality of life for people equally without leaving some people left behind because of whatever circumstances. Otherwise people feel the need to leave with sometimes a couple bangs.
