It was nice to give a mini lecture at our #BADigitalSociety Experience Day! The topic which I addressed were the (corroding) boundaries between politics and the tech economy. Why do democracies ideally need a separation of government and business? Why is this difficult in the case of Big Tech? And why do so many countries now aim for #digitalsovereignty? Going #OpenSource is not always possible, but we can also consider local proprietary IT solutions if we want to avoid the big players.
