WhiteSource heeft geanalyseerd<\/a><\/noindex> In 2019, 67% van alle projecten werden onder permissieve licenties aangeboden, terwijl 33% onder copyleft-licenties viel. Een analyse van 4 miljoen open pakketten en 130 miljoen bestanden met code in 200 verschillende programmeertalen toonde aan dat het aandeel copyleft-licenties gestaag daalt. In 2012 was 59% van alle open projecten onder copyleft-licenties zoals GPL, LGPL en AGPL, terwijl permissieve licenties zoals MIT, Apache en BSD een aandeel van 41% hadden. In 2016 veranderde de verhouding tot 55% in het voordeel van permissieve licenties. <\/p>\n

\"Copyleft-licenties<\/a><\/noindex><\/center><\/p>\n

Volgens een van de leidinggevenden van WhiteSource is het begrip copyleft ontstaan in de tijd van de strijd tegen bedrijven om te voorkomen dat open source code voor eigen gewin wordt gebruikt zonder een tegenprestatie of om verdere verspreiding te beperken. De trend van de toenemende populariteit van permissieve licenties is te wijten aan het feit dat er in de moderne realiteit geen scheiding meer is tussen eigen en vreemd, met betrekking tot de strijd tussen bedrijven en de open source gemeenschap, en ook omdat bedrijven steeds meer betrokken raken bij de ontwikkeling van open source software, waarbij het gebruik van permissieve licenties handiger en veiliger is. <\/p>\n

In plaats van de strijd tussen bedrijven en de gemeenschap, krijgt de strijd tussen cloudproviders en startups die open projecten ontwikkelen steeds meer aandacht. Onvrede over het feit dat cloudproviders afgeleide commerci\u00eble producten cre\u00ebren en open frameworks en databases in de vorm van cloudservices doorverkopen, maar geen bijdrage leveren aan de gemeenschap en niet helpen bij de ontwikkeling, leidt tot een verschuiving van projecten naar propri\u00ebtaire licenties of naar een model Open Core<\/a><\/noindex>. Bijvoorbeeld, soortgelijke veranderingen hebben recentelijk projecten geraakt ElasticSearch<\/a><\/noindex>, Redis<\/a><\/noindex>, MongoDB<\/a><\/noindex>, Timescale<\/a><\/noindex> en CockroachDB<\/a><\/noindex>.<\/p>\n

Ter herinnering, het verschil tussen copyleft en permissieve licenties is dat copyleft licenties vereist zijn om de oorspronkelijke voorwaarden voor afgeleide werken te behouden (in het geval van GPL, is het verplicht om de code van alle afgeleide werken onder GPL te verspreiden), terwijl permissieve licenties de mogelijkheid bieden om de voorwaarden te wijzigen, inclusief de mogelijkheid om code in gesloten projecten te gebruiken.<\/p>\n
