Perhaps that thread should be stickied, then. But those terms outlined still make this not an open source application. From
http://www.opensource.org/docs/definition.php, the official definition
1. Free Redistribution
The license shall not restrict any party from selling or giving away the software as a component of an aggregate software distribution containing programs from several different sources. The license shall not require a royalty or other fee for such sale.
Term 2 of the planescape license puts restrictions on copying, thus violates the definition.
3. Derived Works
The license must allow modifications and derived works, and must allow them to be distributed under the same terms as the license of the original software.
Term 2 violates section 3 of the open source definition by denying the right to create a derived work.
8. License Must Not Be Specific to a Product
The rights attached to the program must not depend on the program\'s being part of a particular software distribution. If the program is extracted from that distribution and used or distributed within the terms of the program\'s license, all parties to whom the program is redistributed should have the same rights as those that are granted in conjunction with the original software distribution.
The terms of the license which disallow the artwork and code from being used on other MMORPGs breaks section 8 of the open source definition.
Also as part of the definition, Open Source licenses govern only the REDISTRIBUTION of the contents. NEVER, EVER, EVER their use. So section 3 of the planeshift license breaks the open source definition.
As is, this license is NOT a valid open source license, and this app is not an open source app.
Also, there is no way that they can claim it applies only to the other content, as the other content has nothing to do with official/non-official servers. Thats a software (code) only issue.
Like I said- if you want to make a proprietary game with open source components of a proper license (liek Crystal space which is LGPLed and can be linked to by proprietary code), thats fine. But don\'t claim its open source.
