Karma is a Bitch
I don't know why you're surprised.
The spyware Zango profited from not only screwed over sponsor progs but also fucked over their affiliates as well. Pretty much it's safe to say on one level or another the company your "brains and skill" made come to life stole from people on almost every level of this industry. If you lay down with dogs you wake up with fleas.
Now that you can see how difficult it is to drive traffic maybe you can respect what it felt like to have some of that traffic stolen from you.
On the bright side Zango had many large clients. Maybe one of them might be willing to bring you on since they don't seem to take issue with rewarding theives.
