Give me a break. Look, if you don't want his personal conduct to factor in, let's look at the percipidous decline in free software (and the rise of copy right BSD/MIT/Apache open source software). Years ago, LLVM was offered to Stallman and the FSF. Due to the idiosyncratic way he chooses to handle his email, he never even got their message. As such: LLVM fell under a BSD-style license. Clang was built on top of it,…
An extremely silly tall tale.
When we released our software under GNU GPL licenses, we didn't write rms to ask for his permission or blessing. We just did release it under the license we felt was best for our vision.
So if llvm was released under different license, this is fully on llvm author. They had reasons to release it under the license that fitted them best.
