L'azienda WhiteSource ha analizzato<\/a><\/noindex> le licenze di 4 milioni di pacchetti open source e 130 milioni di file di codice in 200 diversi linguaggi di programmazione hanno dimostrato che la quota delle licenze copyleft sta diminuendo costantemente. Nel 2012, il 59% di tutti i progetti open source era rilasciato sotto licenze copyleft come GPL, LGPL e AGPL, mentre la quota delle licenze permissive, come MIT, Apache e BSD, era del 41%. Nel 2016, il rapporto si \u00e8 spostato a favore delle licenze permissive, che hanno conquistato il 55%. Entro il 2019, il divario \u00e8 aumentato, e il 67% dei progetti \u00e8 stato rilasciato sotto licenze permissive, mentre il 33% sotto licenze copyleft. <\/p>\n

\"Le<\/a><\/noindex><\/center><\/p>\n

Secondo un dirigente di WhiteSource, il concetto di copyleft \u00e8 emerso durante la lotta contro le corporation per prevenire l'uso del codice open source per fini egoistici, senza un ritorno di valore o limitando la sua ulteriore diffusione. La crescente popolarit\u00e0 delle licenze permissive \u00e8 dovuta al fatto che, nei contesti moderni, non esiste pi\u00f9 una netta divisione tra ci\u00f2 che \u00e8 proprio e ci\u00f2 che \u00e8 altrui, riguardo al confronto tra le corporation e la comunit\u00e0 Open Source, e al fatto che aumenta il coinvolgimento delle corporation nello sviluppo di software open source, che preferiscono e trovano pi\u00f9 sicuro utilizzare licenze permissive. <\/p>\n

In questo contesto, invece di un conflitto tra corporation e comunit\u00e0, sta emergendo un antagonismo tra i fornitori di servizi cloud e le startup che sviluppano progetti open. Il crescente malcontento nei confronti dei fornitori di servizi cloud, che creano prodotti commerciali derivati e rivendono framework open source e sistemi di gestione dei database sotto forma di servizi cloud, senza partecipare attivamente alla comunit\u00e0 o contribuire allo sviluppo, porta a una transizione dei progetti verso licenze proprietarie o modelli. Open Core<\/a><\/noindex>. Ad esempio, cambiamenti simili hanno recentemente interessato progetti ElasticSearch<\/a><\/noindex>, Redis<\/a><\/noindex>, MongoDB<\/a><\/noindex>, Timescale<\/a><\/noindex> e CockroachDB<\/a><\/noindex>.<\/p>\n

Ricordiamo che la differenza tra licenze copyleft e permissive sta nel fatto che le licenze copyleft richiedono necessariamente la conservazione delle condizioni originali per le opere derivate (nel caso della GPL, \u00e8 necessario distribuire sotto GPL il codice di tutte le opere derivate), mentre le licenze permissive consentono di modificare le condizioni, inclusa la possibilit\u00e0 di utilizzare il codice in progetti closed source.<\/p>\n
