About GNU Linux philosophy

Hi everyone,

I'm new to Linux-based distributions and that's why I started reading how history evolved from Richard Stallman, Linus Torvalds, the GNU Project, free software and so much more.

I haven't delved into all the topics yet but from what I understand the very concept of free software implies that everything is considered "truly accessible to anyone". In particular, the Explaining Why We Don't Endorse Other Systems page lists most of the well known Linux based distributions.

So, based on the concept of pure freedom, all users using distributions such as Ubuntu, Fedora, Arch, Debian, and many others don't fully respect what Richard Stallman always hoped to achieve.

I have many friends who have their workflow on these Linux distributions and praise their choice of using a completely free system while, apparently, this is not the case.

Maybe even just adding repositories where there're one or more proprietary software makes the concept of freedom fall. If I use any Linux distribution but then, for example, contaminate it with products like Spotify, Discord, Zoom, or many others, then being on Linux is equivalent to using Windows or macOS, nothing changes.

Attention mine isn't a criticism but only an observation, I would like to have your opinion on this concept. Feel free to correct me and say I'm wrong, I'm here to learn and understand as much as possible about the open-source world.
