\begin{frame}{Digital Freedom}
	{Core Aspects}

	\begin{itemize}[<+(1)-| alert@+(1)>]
		\item \textbf{Human Rights}\\
			{Extension of fundamental rights into digital spaces\\
			(privacy, expression, assembly, access to information).}
			% The right to privacy, expression, assembly, and access
			% to information in the digital realm, without undue
			% surveillance or censorship.

		\item \textbf{Sovereignty}\\
			{Individual and collective self-determination in cyberspace\\
			(digital identity, communication, participation, interoperation).}
			% Control over one's digital identity, communications,
			% and participation in digital society.

		\item \textbf{Economic}\\
			{Freedom from digital monopolies and rent-seeking\\
			(no vendor lock-in, open supply channels).}
			% The ability to participate in digital markets without
			% being subject to platform lock-in, data extraction,
			% or artificial scarcity.

		\item \textbf{Technical}\\
			{Freedom to run, study, redistribute, and modify \textit{software}\\
			(provided by \alert<6->{\textbf{FLOSS---Free/Libre Open Source Software}})}
			% Freedom to control one's digital tools and data - The
			% ability to use, modify, share, and understand the
			% software and hardware that mediates our digital lives.
			% This aligns directly with the four freedoms of
			% Free Software: run, study, redistribute, and modify.

\end{frame}

\begin{frame}{FLOSS}
	{from 20.000ft}

FLOSS = Free/Libre Open Source Software\\
gives users the rights to
\begin{enumerate}
	\item run,
	\item study,
	\item redistribute and
	\item modify it.
\end{enumerate}
\pause
We depend on it. \textbf{FLOSS is everywhere}:\\
\pause
Your smartphone, laptop, online services, bank, goverment,...\\

\large\textbf{How is it funded?}

% The philosophy of FLOSS represents a radical reimagining of how
% software - and by extension, knowledge - should be created and shared
% in society.
%
% Its impact varies dramatically across stakeholders, creating both
% opportunities and challenges that continue to evolve as our digital
% dependency deepens.
\end{frame}

% Funding sources like NGI are emerging - recognition that the
% traditional economic model fails to support the digital infrastructure
% we all depend on.


\begin{frame}{FLOSS Funding}{The Supply Side}

\begin{description}[<+(1)- | alert@+(1)>]
	\item[\sc Large Companies:] longterm, large teams commitments.\\
			\small{F.e.: Browsers, Compilers, Tools, etc}
	\item[\sc Goverment Grants:] National funding programs, EU: NGI.\\
			\small Usually $\sim$60\% of personell costs covered.
	\item[\sc Vendor Stores:] Google PlayStore, Apple AppStore\\
			\small Vendors take a large cut.
	\item[\sc Ad Revenue:] Google Ads etc.\\
			\small Annoying for users, also privacy nightmare
	\item[\sc User Donations:] via paypal, github, gofundme, patreon, etc.\\
			\small Large variance, 0--10.000EUR/month/developer
	\item[\sc Volunteers:] Hobby projects, Students\\
			\small Probably majority of the contributions
