Thanks for the link, but unfortunately your link does not say anything
against my words, FSF has problem with
1. promoting non-free software.
2. making non-free software readily available to install
3. using Linux kernel (instead of Linux-libre)
You say these options make Ubuntu a non-free distro? Ubuntu does not stand
against users who want to install non-free software and unfortunately promote
those non-free software and make them easily reachable. So, it seems that
their policy is different and it does not make them eligible to name Ubuntu
as non-free.
