No, its because Linus Torvalds doesn’t consider libre software to be important. Torvalds sucks when it comes to free software.
GNU Hurd is an incredibly important project because there can’t be just one “free software kernel.”
Richard Stallman doesn’t care about popularity. He already changed the world. What he does care about is people forgetting their commitment to freedom.
He doesn’t give a shit if people say Linux, he does give a shit if people are “marketing” Linux without an emphasis on freedom.
