What we're talking about is Free Software, or software that respects
essential freedoms that the user of software should always have. All software
in Trisquel's repositories respect these four freedoms.
These freedoms are:
- The freedom to run the program, for any purpose (freedom 0).
- The freedom to study how the program works, and change it so it does your
computing as you wish (freedom 1). Access to the source code is a
precondition for this.
- The freedom to redistribute copies so you can help your neighbor (freedom
2).
- The freedom to distribute copies of your modified versions to others
(freedom 3). By doing this you can give the whole community a chance to
benefit from your changes. Access to the source code is a precondition for
this.
Now, let's take a look at Adobe Flash. It gives you the ability to run the
program. It doesn't give you the freedom to study or redistribute modified or
even unmodified copies of the software. That makes the program non-free.
Therefore, we won't endorse or help out with installing the program. If
you're going to rely on proprietary software, maybe it'd be better for you to
stick with Ubuntu for now.
