I've just visited qrzcq.com and I see no similarity to qrz.com. It's just another website. Nothing more. And, I see some interesting features that are unique.
Please list what you feel is being stolen by qrzcq.com and I'll take another look.
Qrz.com doesn't have the sole right to a database of call signs. In fact, competition means choice. Qrzcq.com is based in Germany. HamQTH.com in the Czech Republic. China has qrz.cn and Russia has an own database/website as well. You are free to support the one you like best, but please don't start calling names to the ones you are not familiar with.
