I did say "relatively speaking." I wasn't making a judgment as to whether it was moral or immoral, just that 4chan as a whole mostly saw it as reasonable, which is why most of them found the intrusion humorous instead of an affront.

This is in stark contrast to when UG Nazi hacked 4chan a while ago by hijacking Cloudflare's CEO's Gmail and pointing 4chan.org's A record at their own server.
