It's cool for a variety of technical reasons, but if you just want to run a booter, you're better off using reflection attacks today than a botnet. Things like proxying web traffic to random home machines, performing layer 7 attacks on webapps, etc are pretty nice from a technical perspective and I think a lot of tech people can appreciate them in that aspect.
But that's pretty much where it ends. They don't make easy money like ransomware does. Ransomware produces customers, doesn't require hard business side work to acquire them, doesn't have competition, etc. From a business perspective, ransomware is just better.
EDIT: Your Tor automation solution seems pretty cool - do you use a VPN to authenticate things or are you relying on the privacy of your .onion names?
