"""I am often seen arguing against LLVM on purely philosophical grounds from my asserted position in the world of open devices and jailbreaking; specifically that it, and Clang, are now products heavily funded (nearly owned) by Apple with the goal of decreasing their reliance on a project (gcc) that was relicensed under GPLv3, an event that caused Apple to immediately retract all of their engineers from contributing code, or even merging newer versions"""

No, he means whats a valid, actual, technical reason to hate.

Also, not it's not just the GPLv3 transition --thought that gave Apple migrating away a huge boost--, it's also tons of technical inefficiencies in the ancient design of GCC.

As an example, you couldn't do XCode style AST-aware autocompletion with GCC without tons of hurt.
