I don't see your point. The current BSD license does, all in all, allow you to do whatever you want with the product. So there will be no: * forced upgrades (No one can force you to upgrade.) * mandatory incompatibilities (No one can mandate anything, you can fix everything yourself.) * disappearance of the product (If you have the source, you have it and can continue to develop it.) You seem to be believing that with the BSD license someone can take over the product and retroactively re-license it. This is false on both counts: No one can take it over unless he buys out the copyright of each contributor (but no open source license prevents that), and no one can revoke the currently granted license. (Well, there is a faction of legal experts that believe that gratis licenses are revokable, but then every such license would be affected.) > As I see it, the only realistic objection to the GPL comes from those > who want to sell copies of the software, or software products based > upon it. The major pragmatic objection to the GPL license has been that it creates legal hassles which we currently don't have. If we allow anyone to use the product at will then we don't have anything to enforce. If we cover our own work with a bunch of conditions then we always have to worry about what we can do with the code and what we can't. > Most people in the "business community" have no such interest, But some do and there's no point in stopping them. -- Peter Eisentraut Sernanders väg 10:115 peter_e@gmx.net 75262 Uppsala http://yi.org/peter-e/ Sweden
