More improvements based on feedback from Lukas and Jie.

- Explain that we had pre-Free Software Movement scenario, to give
  more context.

- Mention the term "proprietary".

- New section "A bit about licenses", with stuff about copyleft and
  permissive.

- Un-texttt "GNU".

- New section "More than just code", with a preparation for the
  "upstream" section.

- Mention Matrix and Rocket.chat.

\section{A bit about licenses}
\begin{frame}{A bit about licenses}
In a nutshell, when we talk about Free Software licenses, we have
two main types:
\newline
\begin{itemize}
\item{\textbf{Copyleft} licenses: \emph{Share-alike} licenses,
which guarantee that the work will be redistributed (modified or
not) under the same terms as the original license.
\textbf{GPLv3} is the main license in this field.}
\item{\textbf{Permissive} licenses: Allow redistribution under
other terms, \textbf{even non-free!} Main licenses here are
\textbf{Apache 2.0} and \textbf{MIT/Expat}.}
\end{itemize}
