"Fortuitously, Apple eventually discovered a technically brilliant (but sadly non-copylefted) research programming language and compiler system called LLVM."
What does he mean by that ?
Did LLVM already exist in various pieces and apple "discovered" it by putting them together ?
Or is he purposely using the word "discover" to suggest that you can't invent a programming language (since programming is all reducible to math) and that new languages are merely "discovered" ?
They discovered that the University of Illinois had been working on a compiler back-end called LLVM, and that being permissively licensed they could use it as a shortcut to making a proprietary compiler without putting in all the work.
By being permissively licensed, it was free from all the garbage and ideological baggage that GCC has, so they could use it in meaningful ways besides being just a compiler. Like using it to do analysis on code in the IDE.
That's because LLVM have those features, not because it has that license. A program designed to do analysis on code in the IDE will still do it even if the program is proprietary, which is the inevitable consequence of promoting permissive licenses.
