The part "earning what other people are doing to earn money independently using Racket." is interesting in itself - people may answer while you may check presentations at RacketConf where there are comercial usages of Racket.
Take my answer with a large pinch of salt but here is gist: The DrRacket distribution is LGPL3 - you may use it, change it, distribute it and distibute changes to it under LGPL i.e. every time you distribute it you will have to provide the source (under same licence). You cannot impose more obligations or weave obligations stemming from that. Since Racket licence is LGPL you may distibute your modules that link to it and there are basically no obligations for those modules. Those additional modules may impose whatever conditions you want. Thus you might distribute them in the binary format of Racket, you may distribute in source form - and no matter what way you do the distribution you may demand payment for whatever usage - commercial or not. You may prevent changes or distribution of changes. "enforcing" would have to be done via the court system - for example when someone uses your modules in a way different from your license. Now - what comprises linking (as different to 'derivative work') is a convoluted matter. FSF site will be helpful in that yet the legal practice may be different in different countries. The sentence "the Racket license does not restrict you at all" means it does not restrict your modules. In a wider sense it also means that your usage of Racket is not restricted, but distribution of Racket (AKA conveying) is a different matter (and there are conditions on that) Kind regards: al_shopov На пт, 23.08.2019 г. в 17:02 ч.
