@mholiv@lemmy.world It looks you believe that magic letters G, P and L make company release their improvements to the public. Actually they do the same with MIT and GPL code: include it into closed source products and that is. Because there’s no way for you to check if there was GPL in closed source program.
But the GPL style licences bring licence compatibility issues while MIT style do not. (And that’s why Linux cannot include ZFS driver despite it’s being “GPL style” licenced)
@mholiv@lemmy.world Going criminal is not a goal in itself. I think you know, corporations exist for profit. If violating a licence gains profit they’ll do it. You know companies doing open source? I know too. Why do they do it? Because of GPL? No, they do because they profit from it. (And they like how copyleft licences restrict others from benefiting).
You see problem with CDDL? Problem would be any other copyleft licence. No copyleft licence is compatible with GPL (except they include special exception), neither CDDL, nor GFDL (despite GNU in its name), nor any other. Funny you mention MIT, MPL, Apache and BSD in this list, because they’re all permissive that are compatible to both GPL and CDDL. It is not CDDL, but copyleft making these licences incompatible. I mentioned CDDL specifically because it is an iconic example how copyleft (allows a company to) hurt open source.
You’re speaking about “conspiracies”, and ask me for proofs. But what proofs do you need? That companies violate licences? There are known cases of open source licence litigations. Actually problem is deeper, not that companies violate licences, but that there’s no effective way to enforce such licences (without totalitarism).
