Ton Roosendaal, criador do sistema de modelagem 3D Blender, publicou<\/a><\/noindex> reafirmou que o Blender foi e sempre ser\u00e1 um projeto livre, licenciado sob a licen\u00e7a GPL e dispon\u00edvel sem restri\u00e7\u00f5es para qualquer uso, incluindo aplica\u00e7\u00f5es comerciais. Ton destacou que todos os desenvolvedores do Blender e dos plugins que utilizam a API interna e que s\u00e3o obrigados a abrir o c\u00f3digo de seus desenvolvimentos sob a GPL, est\u00e3o contribuindo para um esfor\u00e7o comum e concordam desde o in\u00edcio que, ao utilizarem o trabalho dos outros, eles tamb\u00e9m permitem que seu pr\u00f3prio contributo seja utilizado sob as mesmas condi\u00e7\u00f5es.<\/p>\n

A raz\u00e3o para recordar a natureza livre do projeto foi gerou descontentamento<\/a><\/noindex> a preocupa\u00e7\u00e3o de muitos desenvolvedores de plugins com o surgimento de um novo servi\u00e7o Blender Depot<\/a><\/noindex>, que permite escolher os plugins de interesse para o Blender e depois baix\u00e1-los e instal\u00e1-los de uma s\u00f3 vez. <\/p>\n

O problema \u00e9 que, apesar de todos os plugins para o Blender serem obrigados a publicar seu c\u00f3digo sob a licen\u00e7a GPL, recentemente come\u00e7ou a pr\u00e1tica de vendas de plugins por seus autores atrav\u00e9s do cat\u00e1logo de loja Blender Market<\/a><\/noindex>. Os plugins s\u00e3o abertos, mas seus autores t\u00eam o direito de fornecer pacotes de instala\u00e7\u00e3o atrav\u00e9s de um servi\u00e7o de download pago. A GPL n\u00e3o pro\u00edbe tal venda, que permite aos autores obter recursos para o desenvolvimento cont\u00ednuo de seus plugins.<\/p>\n

O Blender Depot utiliza o c\u00f3digo GPL existente dos complementos para distribui\u00e7\u00e3o gratuita, o que mina o modelo de neg\u00f3cio estabelecido. Por exemplo, o complemento RetopoFlow \u00e9 oferecido para download em Blender Market<\/a><\/noindex> por $86, mas absolutamente gratuito para instala\u00e7\u00e3o atrav\u00e9s de Blender Depot<\/a><\/noindex> ou download manual do c\u00f3digo de GitHub<\/a><\/noindex>. Al\u00e9m disso, se desejado, \u00e9 poss\u00edvel criar<\/a><\/noindex> um servi\u00e7o pago e vender pacotes \u00e0 margem dos autores (por exemplo, essa pr\u00e1tica de venda de produtos formados a partir de componentes GPL \u00e9 adotada por distribui\u00e7\u00f5es comerciais do Linux).<\/p>\n

Do ponto de vista jur\u00eddico, tal pr\u00e1tica \u00e9 totalmente legal, pois a GPL permite a distribui\u00e7\u00e3o do produto sem restri\u00e7\u00f5es. Mas os desenvolvedores de complementos pagos para o Blender est\u00e3o insatisfeitos com as a\u00e7\u00f5es do Blender Depot e iniciaram discuss\u00f5es<\/a><\/noindex> a \u00e9tica na cria\u00e7\u00e3o de servi\u00e7os para a distribui\u00e7\u00e3o gratuita de produtos GPL, como uma forma de contornar os canais de distribui\u00e7\u00e3o pagos utilizados por seus autores, bem como a viabilidade de aplicar a GPL em um projeto e a possibilidade de usar uma licen\u00e7a separada para a API fornecida. Segundo alguns desenvolvedores, a oportunidade de receber uma recompensa foi a respons\u00e1vel pela cria\u00e7\u00e3o de muitos complementos \u00fateis para o Blender, e o surgimento de servi\u00e7os como o Blender Depot pode amea\u00e7ar a ecossistema estabelecida.<\/p>\n
