Shame on him! The point is that according to the GPL, he MUST indicate clearly that Celestia may be obtained FREE...

Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable

Seeker 3D is a new program from Software Bisque, and a lot more like Celestia than TheSky is. It's purely a solar system simulator, though; it's not possible to visit other stars.

This was his reply,"Celestia is GNU GPL licensed software. Apex Software is a legal and authorized distributor. Please do not send us any additional harassing emails.
Thank you,

So, he can do this with NO PROBLEM??
