I read an interesting article recently: https://www.wired.com/story/mirai-botnet-minecraft-scam-brought-down-the-internet/
I don't remember exactly what it was about that article that I wanted to write about, but it's definitely an intersting read. The story is basically how a company who wanted to protect Minecraft servers from DDoS attacks actually created a tool to provide DDoS attacks.
It's interesting, because you could argue that that is the most capitalistic view: you create the supply and the demand, which is great! But obviously it's a problem, because that's terrible.
I'm not sure what the answers should be, but it's a good read, I highly recommend it.
