What Do You Think of Selling OpenCPN?

[esan6]

First, I like to thank you for such a nice software suite. I have just downloaded it in the past week and have learned a bunch of it's capabilities. I just need to get a good receiver and to test it out completely.
Second, and the primary reason for this email. I was on ebay today looking to buy a usb reciever and noticed someone selling a piece of software. As I looked into it the software seemed to resemble OPENCPN in many ways. I was going to ask them about it but decided to post this in the forum to get your take on this.

Here is the item number 280846487576 as posted on ebay. Now if this is you guys just trying to cover costs then so be it. But if it is someone who is ripping you off then I feel you should know about it.
