Ton ha sottolineato che tutti gli sviluppatori di Blender e dei plugin che utilizzano l'API interna e sono obbligati a rendere pubblico il codice dei loro sviluppi sotto GPL, contribuiscono a un obiettivo comune e accettano fin dall'inizio che, usufruendo del lavoro altrui, permettano alle stesse condizioni di utilizzare anche il proprio contributo.<\/p>\n<p>Il motivo per ricordare la natura libera del progetto \u00e8 stato <noindex><a rel=\"nofollow\" href=\"https:\/\/blenderartists.org\/t\/introducing-blender-depot-browse-and-batch-install-blender-add-ons\/1162742\">discontento<\/a><\/noindex> di molti sviluppatori di plugin l'emergere di un nuovo servizio <noindex><a rel=\"nofollow\" href=\"https:\/\/blenderdepot.netlify.com\/\">Blender Depot<\/a><\/noindex>, che consente di selezionare i plugin di interesse per Blender e poi scaricarli e installarli tutti in una volta. <\/p>\n<p>Il problema \u00e8 che, nonostante tutti i plugin di Blender siano obbligati a pubblicare il loro codice sotto licenza GPL, recentemente \u00e8 diventata abituale la vendita di plugin da parte dei loro autori attraverso un catalogo negozio <noindex><a rel=\"nofollow\" href=\"https:\/\/blendermarket.com\/\">Blender Market<\/a><\/noindex>. I plugin sono aperti, ma i loro autori hanno il diritto di fornire pacchetti di installazione tramite un servizio di download a pagamento. La GPL non vieta tale vendita, che consente agli autori di ottenere fondi per lo sviluppo ulteriore dei loro plugin.<\/p>\n<p>Blender Depot utilizza il codice GPL esistente per le estensioni per la distribuzione gratuita, il che mina il modello di business consolidato. Ad esempio, l'estensione RetopoFlow \u00e8 offerta per il download a <noindex><a rel=\"nofollow\" href=\"https:\/\/blendermarket.com\/products\/retopoflow\/\">Blender Market<\/a><\/noindex> per $86, ma \u00e8 assolutamente gratuita per l'installazione tramite <noindex><a rel=\"nofollow\" href=\"https:\/\/blenderdepot.netlify.com\/addons\/CGCookie\/retopoflow\">Blender Depot<\/a><\/noindex> o il download manuale del codice da <noindex><a rel=\"nofollow\" href=\"https:\/\/github.com\/CGCookie\/retopoflow\">GitHub<\/a><\/noindex>. Inoltre, se lo si desidera, <noindex><a rel=\"nofollow\" href=\"https:\/\/www.opennet.ru\/opennews\/art.shtml?num=29456\">\u00e8 possibile creare<\/a><\/noindex> un servizio a pagamento e vendere pacchetti a scapito degli autori (ad esempio, una vendita di un prodotto formato da componenti GPL \u00e8 praticata dalle distribuzioni Linux commerciali).<\/p>\n<p>Dal punto di vista legale, tale pratica \u00e8 completamente legale, poich\u00e9 la GPL consente di distribuire il prodotto senza restrizioni. Tuttavia, gli sviluppatori di estensioni a pagamento per Blender non sono contenti delle azioni di Blender Depot e <noindex><a rel=\"nofollow\" href=\"https:\/\/blenderartists.org\/t\/yet-another-discussion-about-the-gpl-this-time-about-add-ons-again\/1163319\">hanno iniziato una discussione<\/a><\/noindex> l'etica nella creazione di servizi per la distribuzione gratuita di prodotti GPL eludendo i canali di fornitura a pagamento utilizzati dai loro autori, cos\u00ec come l'opportunit\u00e0 di applicare la GPL nel progetto e la possibilit\u00e0 di utilizzare una licenza separata per le API fornite. Secondo alcuni sviluppatori, la possibilit\u00e0 di ricevere compensi ha portato alla creazione di molti utili componenti aggiuntivi per Blender e l'emergere di servizi come Blender Depot potrebbe portare alla distruzione dell'ecosistema esistente.<\/p>\n<p><noindex><a rel=\"nofollow\" name=\"link\"><\/a><\/noindex><\/p>\n<p>Fonte: <a \ncontent=\"nofollow\" rel=\"nofollow\"
