RMS specifically has prevented GCC from being innovative in ways that would complicate the enforcement of the GPL until the new feature is required to be competitive. First, that is not freedom. Second, that policy may have been viable when GCC was the only viable challenger to proprietary compilers, but not when Open Source compilers with more commercially friendly licenses exist.
The FSF is fighting the last war and believes that corporations are trying to tear down the FSF and the GNU Project software. It's a fantasy to convince themselves that they are relevant.
Richard was a great visionary and is useful to expand the Overton window, but the FSF has not evolved to advocate for a pragmatic approach. If RMS and the FSF wishes to advocate for a purist ideology, that's fine, but they need to accept that it severely limits their appeal and ability to shape policy, even if they are "right".
