Ehh, I'm not sure it's fair to call the FSF dynamic linking absolutists. They only care about any of this because they've boxed themselves into a corner. They want to prevent people from writing proprietary wrappers around copyleft programs, but they don't want a license so restrictive that proprietary and copyleft programs are forbidden from interacting, and Freedom 0 means they can't explicitly prohibit a copyleft program from being used for suchandsuch purpose.
