LLVM and clang can be used in pretty much any project. They have provided every developer tools to use in anyway we wish. GCC's parts cannot be included in other projects because they are licensed in such a way that tells us that the GCC code is more important than the code we are using. Why does a 1,000 line GPL count for more than 100,000 lines of some other license?

I think the best community is a voluntary one, and with security the way it is, I would rather developers who don't want to be part of the community benefit from the code just as I like the idea of everyone (who can) being vaccinated.

GPL generates a self-selected community that has barriers to participation with other communities because the GPL code is held as more important than the rest.
