One issue you would encounter is that deciding what is a "commercial" use can be difficult. This comes up with Creative Commons licenses ( https://creativecommons.org/faq/#does-my-use-violate-the-noncommercial-clause-of-the-licenses ):
> … there will always be uses that are challenging to categorize as > commercial or noncommercial. CC cannot advise you on what is and is not > commercial use. > CC has a 255-page study titled "Defining 'Noncommercial'" which they clarify does not, in fact, define "noncommercial." However, regardless of whether you *should* do this, I believe you can. The LGPL governs your use of Racket itself in your product: it does not dictate the terms of the license you use for your code (except that people must be allowed to re-link your code with new/modified versions of Racket). I can write programs in Racket and release them under the AGPL; someone else can release their Racket programs under an entirely non-free proprietary license. If you want to use a license to charge money only to "commercial" users, you can find or create a license that (hopefully) expresses your intent. However, such a license would not meet the definition of "open source" or free/libre software, due to "discrimination against fields of endeavor" (https://opensource.org/osd). (I am not a lawyer; this is just my understanding as a creator and user of software.) -Philip On Fri, Aug 23, 2019 at 10:02 AM Stephen De Gabrielle < spdegabrie...@gmail.com> wrote: > Hi Sig, > > GNU provides they reason why not to use LGPL: > https://www.gnu.org/licenses/why-not-lgpl.html > > Location licence in racket repository: > https://github.com/racket/racket/blob/master/racket/src/COPYING_LESSER.txt > > - Github has a summary of what they think the meaning of LGPL is > https://choosealicense.com/licenses/ > > GNU also provides this; https://www.gnu.org/licenses/lgpl-java.html which > I *believe* mirrors what is written at > https://download.racket-lang.org/license.html > > I hope this helps. > > Kind regards, > > Stephen > > > On Friday, August 23, 2019 at 10:25:02 PM UTC+9, sage wrote: >> >> --I believe this email was lost due to me not being subscribed to the >> list last time I sent it.
