It's just kind of stupid honestly. This benefits no one, it's this shitty behavior that has existed for years in the gaming community. Hackers target devs and ruin entire projects for what? Some pre release content. Some test videos of early builds? The shit is stupid.
I know they do it to extort the devs, to prove they can, and because it's this insular group of people focused on shit like this that have made this their purpose.
But it's honestly. Just stupid. They're all losers. Sometimes you lose the forest for the trees and can't see just how pathetic you've become. That's all these guys. Complete losers.
