Did EVGA Steal The Rivatuner RTSS Design?

What's that you say? It's been a while since we've had any controversy in the industry? Here's some for you. Problem solved. So was this modern age stealing ? Well, you can't copyright a GUI / user-interface so sure, EVGA is allowed to do this as long as they didn't 'borrow' code from the RTSS engine (I am trying to choose my words carefully here). But dear dudes and dudettes from EVGA, if you launch a totally new in-house designed overclock utility and you want something new. Why then copy-paste the Rivatuner and RTSS design this much ?
