Re: What TheHackerGiraffe has accomplished
Attackers of people's Chromecast and printers, of course. Yes, those people should not have left the door open, but that in no way makes TheHackerGiraffe's actions acceptable, any more than it's acceptable to walk into someone else's house just because they left their door unlocked.
Also, it's clear the TheHackerGiraffe has no actual interest (even misguided) in helping people to secure their shit. His interest was finding and exploiting vulnerable systems in order to advertise Pewdiepie's channel.
