I disagree: we do not only promote Trisquel, we promote freedom. This is the
greater goal. A user committed to freedom will not switch back to proprietary
software for technical convenience.
That said, your third point is more about ethics (i.e., about "controlling
your computing") than it is technical. However, I am not sure it deserves to
be part of a small argumentation in favor of Trisquel.
Although the last point is technical, it could be simplified into "a huge
amount of free software readily available from Trisquel's repository
(including all applications in Ubuntu's repositories but the non-free ones)"
and be included in the text.
