You mean simple things. The preamble to the GPL is longer than the entire ISC license... by like 5 times. GCC is like 100 times more complex than PCC. BSD folks like simple, secure things.

To add some numbers to that, PCC appears to be about 20,000 lines of code [1] and LLVM+clang together about 550,000 lines [2]. I can't immediately find a figure for GCC, but I wouldn't be surprised if it was significantly more than LLVM+clang.
