> IT companies are leveraging a huge value from OSS without providing enough back to pay developments of more OSS. It is one of the biggest injustices currently happening in the "rich world", but there is no easy fix. GPL?
As someone who likes the GPL and supports the idea that all software should be Free, the thing that bothers me about it is how "closed" it is to projects based on other Free licenses. GPL projects "take" from BSD/MIT/Apache/etc projects (in the form of libraries, supporting software, etc) and only give back with conditions they can't accept. You can say it's on them, for choosing the license they chose, they accepted…
LLVM is a great project and brought the possibility of .NET/Java tooling to C and C++, but just check the amount of GPU shader drivers, Swift and some embedded compilers for examples of companies abusing BSD/MIT/Apache/etc projects.
