Here is a draft I have come up with (no formatting):
I would recommend you try Trisquel GNU/Linux. Trisquel is a system endorsed
by the GNU project which contains only free (libre) software which is
software that respects your freedoms. It is a derivative of Ubuntu meaning
it is just as accessible and user friendly.
However, Trisquel has advantages over mainstream distros like Ubuntu and
(GNU) Linux Mint. Source code for every single package in Trisquel is free
to run, study, modify, and share. Other distros take shortcuts and include
proprietary software like skype (owned by Microsoft) which lacks these
freedoms. These shortcuts can lead to malicious features or digital
restrictions. Trisquel and other free distributions do not make these sorts
of compromises on your freedoms. With distros like Trisquel you really are
in the driver's seat concerning your software.
Those are the reasons you should try freedom and try Trisquel GNU/Linux.
