F\u00f6retaget WhiteSource har analyserat<\/a><\/noindex> Genom att analysera 4 miljoner \u00f6ppna paket och 130 miljoner filer med kod p\u00e5 200 olika programmeringsspr\u00e5k kom man fram till att andelen copyleft-licenser stadigt minskar. \u00c5r 2012 levererades 59 % av alla \u00f6ppna projekt under copyleft-licenser s\u00e5som GPL, LGPL och AGPL, medan andelen permissiva licenser som MIT, Apache och BSD stod f\u00f6r 41 %. \u00c5r 2016 f\u00f6r\u00e4ndrades f\u00f6rh\u00e5llandet till f\u00f6rm\u00e5n f\u00f6r de permissiva licenserna, som er\u00f6vrade 55 %. Fram till 2019 \u00f6kade skillnaden och 67 % av projekten levererades under permissiva licenser, medan 33 % var under copyleft. <\/p>\n

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

Enligt en av cheferna p\u00e5 WhiteSource uppstod begreppet copyleft under tiden av motst\u00e5nd mot f\u00f6retag f\u00f6r att f\u00f6rhindra anv\u00e4ndning av \u00f6ppen kod i egenintresse utan \u00e5terkoppling eller begr\u00e4nsning av vidare distribution. Trenden med \u00f6kad popularitet av permissiva licenser beror p\u00e5 att det i dagens verklighet inte l\u00e4ngre finns n\u00e5gon uppdelning mellan oss och dem, n\u00e4r det g\u00e4ller motst\u00e5ndet mellan f\u00f6retag och Open Source-gemenskapen, samt att f\u00f6retagens engagemang i utvecklingen av \u00f6ppen programvara \u00f6kar, vilket g\u00f6r det enklare och s\u00e4krare f\u00f6r dem att anv\u00e4nda permissiva licenser. <\/p>\n

Ist\u00e4llet f\u00f6r motst\u00e5ndet mellan f\u00f6retag och gemenskap f\u00e5r motst\u00e5ndet mellan molnleverant\u00f6rer och startups som utvecklar \u00f6ppna projekt allt st\u00f6rre betydelse. Missn\u00f6jet med att molnleverant\u00f6rer skapar derivat av kommersiella produkter och s\u00e4ljer \u00f6ppna ramverk och DBMS som molntj\u00e4nster, utan att delta i gemenskapens liv eller hj\u00e4lpa till med utvecklingen, leder till att projekt \u00f6verg\u00e5r till propriet\u00e4ra licenser eller modeller Open Core<\/a><\/noindex>. Till exempel har s\u00e5dana f\u00f6r\u00e4ndringar nyligen p\u00e5verkat projekten ElasticSearch<\/a><\/noindex>, Redis<\/a><\/noindex>, MongoDB<\/a><\/noindex>, Timescale<\/a><\/noindex> och CockroachDB<\/a><\/noindex>.<\/p>\n

L\u00e5t oss p\u00e5minna om att skillnaden mellan copyleft och permissiva licenser ligger i det faktum att copyleft-licenser obligatoriskt kr\u00e4ver att ursprungliga villkor f\u00f6rderivatan av arbeten bevaras (i fallet med GPL kr\u00e4vs det att koden f\u00f6r alla derivatverk sprids under GPL), medan permissiva licenser ger m\u00f6jlighet att \u00e4ndra villkoren, inklusive att anv\u00e4nda koden i st\u00e4ngda projekt.<\/p>\n
