From this context, we reflect on what margins the Internet leaves to exercise our rationality and freedom, through active and free participation, fundamental rights of citizens, understood as essential elements of the democratic ideal. It is based on what should be an ideal type of technology at the service of de-mocratic values, using the Internet as a common good for citizens. From this perspective, the text reflects on the use of advertising and political marketing on the internet. It contains some inter-pretations of what would be a common space on the Internet as a democratic ideal. To make this analysis, the notions of rationality and freedom of Amartya Sen and Michel Foucault are used to contrast two dimensions of democracy, one more deliberative, which is in line with the idea of the common good of Ostrom (2000). It would correspond to a democracy by discussion, according to Amartya Sen. The other dimension would correspond to a democratic model with oligarchic tou-ches, in a neoliberal economic context, more in a line of rationality linked to power relations and market interests, following Foucault. Freedom is important to both, based on the participation and public debates according to Sen and the critical attitude of the individual according to Foucault.
