Do you agree or no?

I see a lot of people that want to switch from windows to a linux distro or a open os. But from what i see they tend to migrate to another black boxed/closed os.

What is a trully free os that doesnt included any closed code/binary blobs/closed drivers etc.

Just 100% free open code, no traps.

What are the options and what should one go with if they want fully free os that rejects any closed code?
