While all the projects you mention share the paramount goal of freedom for users, all of them have other specific goals, and that's why they are individual projects:
They are also part of the GNU system, LibreJS is part of the GNU project, and Xiph is a project that both the GNU project and the FSF support. But their goals are simple: make non-free software irrelevant in a specific domain -- which is why GNU also exists. I suggest you visit the GNU web site, and read the whole section on philosophy (https://www.gnu.org/philosophy/), maybe that will clear things up for you. As it stands, you are immensly confused what the GNU project and the FSF are about, what their history is and what their mission is. To end this discussion I will quote Richard from 1983 as to why GNU exists at all: I consider that the golden rule requires that if I like a program I must share it with other people who like it. I cannot in good conscience sign a nondisclosure agreement or a software license agreement. So that I can continue to use computers without violating my principles, I have decided to put together a sufficient body of free software so that I will be able to get along without any software that is not free.
