That's just it, all of what I described were him attacking other Free programs. Telling someone to delete mentions of a Free compiler because it could potentially be used by someone to improve proprietary software harms those working on Free software much more than those working on proprietary software, and discourages future people from working on more challenging free products. His claims of LLVM being an attack from Apple are factually questionable, given that Apple hasn't been a majority contributor to LLVM for a considerable amount of time, plus LLVM being used in a number of Free projects, like Xorg. While he's kept the same dogma, he's not kept up with what users expect from their tooling.
I understand he doesn't care about popularity, however, how can you sustain a Free ecosystem if your tooling is generations behind what's available in other, still free, ecosystems. All the small compromises in the world don't matter if you're not willing to listen to people describing what is currently wanted and needed for modern software development. While Stallman has indeed kept the same ideological course, he's not kept up with the social aspects of the industry, to the detriment of everyone. That's the part that he needs to change.
