Hofori idzi dzakazivisa kuti dzinotarisira kusimudzira kufungidzira kukuru kwemarezinesi eakavhurika, vachizvipira kuwedzera kodzero dzekugadzirisa zvikanganiso zvekuteerera. Zvese zviito zvakanaka zvinobatsira ese iwo mapurojekiti akabatwa nerudzi urwu rwemahara kana akavhurwa masosi marezinesi uye ayo dzimwe nguva asina zvivimbiso zvavanofanira uye nekudaro iyi quartet ine simba ichasimwa kuisimbisa.
Rezinesi rakakurumbira GNU GPL (General Veruzhinji License) Ndiyo imwe yeanonyanya kushandiswa nhasi, pamwe neLGPL (kana Lesser GPL) yemapurojekiti emahara software. Uyezve, sezvatinoziva, iyo GPL ndiyo inoshandiswa kune mazhinji eLinux kernel (kunze kweavo vatyairi vakaremerwa semodules uye vanogona kunge vari pasi pemamwe marezinesi, kusanganisira evaridzi vevatyairi vatinodaidza mabhinari blobs) uye zvakare yeGPL.yakasara yeGNU system inoita kugovera kwedu, kusanganisira akawanda emasoftware mapakeji anoshandiswa mairi. Neshanduro yekutanga neyechipiri yeGPL mimwe mikana yakanga isipo, asi neshanduro 3 yeGPL (GPLv3Ehe, chirevo chekumisa chaicho chakabatanidzwa icho chakapa vashandisi kugona kugadzirisa zvikanganiso mukuteerera rezinesi. Izvi zvakapa nzira inonzwisisika yezvikanganiso uye zviputi zvaimboenda zvisingaonekwe, zvichibvumidza kutevedzwa kwelayisensi uye kuenderana nezvinodiwa munharaunda
Zvakanaka, IBM, Google, Red Hat neFacebook vakazvipirawo kuwedzera nzira yeGPLv3 yekukanganisa marezenisi ekuteerera kodhi yesoftware iyo marezinesi ega ega pasi pedzimwe shanduro senge GPLv1, GPLv2, GPLv2.1.
