This is interesting, I did not know that...


"Despite our best efforts, the FSF has never considered the Apache
License to be compatible with GPL version 2, citing the patent
termination and indemnification provisions as restrictions not present
in the older GPL license."

It seems to be compatible with GPLv3, though. But I think most
companies that use LLVM are stuck with GPLv2 due to the patents issue.
