I've made a photo where it all started with me and privacy: https://shares.sebastix.dev/y5avPXEZ.jpeg (it's Dutch)
Part of my thesis called "a digital lifeline" I've written in 2009-2010 (in Dutch). In this paper I researched where are all my digital artefacts are going and how I could collect them to get them back in a personal archive. Back then I already stated that BigTech were not social and only care about your data to sell it as much as possible. I remember that http://suicidemachine.org/ was in the news because Facebook was blocking that tool to delete your profile.
